FOR IMMEDIATE RELEASE

Southwest Idaho highway construction report for June 14-21

BOISE - The following projects in southwest Idaho are now under way or will begin soon.

ADA COUNTY
BOISE - Idaho 16 Extension, river crossing and local road connections (GARVEE)

The next step in the extension of Idaho 16 connecting State Street to Chinden Boulevard is set to begin within a few weeks. These improvements will be done in late summer 2014.

Contracts have already been awarded to connect State to Chinden, including a new 1,726-foot bridge. Work has been under way since last May to build bridges across the Boise River and Phyllis Canal between U.S. 20/26 and Idaho 44. Work will begin soon on the local roads connecting the bridge.

Construction crews completed work on the south shoulder of Idaho 44 to prepare for the construction of the new Idaho 16 alignment.  After the Fourth of July holiday, construction crews will begin work on the north side of Idaho 44 in the project area and traffic will shift to the south side of Idaho 44.  As crews continue to prepare for this traffic shift, motorists are encouraged to use caution when driving in the area.    

GARVEE (Grant Anticipation Revenue Vehicle) bonds allowed the Idaho Transportation Department to advance critical infrastructure improvements in vital corridors throughout the state.

Concrete Placing Co., of Boise, and Idaho Sand & Gravel, of Nampa, are the prime contractors on these projects. Knife River Const., of Boise and Nampa Paving are two of the main subcontractors for this work. The total construction cost is $38.94 million.

ADA COUNTY
MERIDIAN - Eagle Road resurfacing and medians

This project resurfaced Idaho 55 from Fairview Avenue in Meridian to State Street in Eagle, and installed raised medians from Franklin to Oakhampton Drive, one-half mile north of Chinden Boulevard.

A new signal is being installed at Wainwright Street and Eagle Road. The new signal will improve traffic flow and help reduce delays on Eagle Road between Interstate 84 and Idaho 44. It is expected to be in operation by mid-July.

Through early July, crews will continue work on the road shoulder. All lanes will remain open during the day. One lane will remain open in each direction during nighttime construction. The nighttime work hours are 9 p.m. to 5 a.m. on weekdays and 9 p.m. to 8 a.m. on weekends.

One of the last tasks will be to re-stripe Eagle Road in the project area.

Idaho Sand & Gravel Co., of Nampa, is the contractor on this $4.7 million project.

ADA COUNTY
State Street/Linder Road/Ballantyne Lane intersection work

This work is part of the department’s Idaho 44 improvement project from Linder Road to Ballantyne Lane. Over the next several months, crews will be rebuilding the Idaho 44/Linder Road intersection and widening Idaho 44 to five lanes.

Flaggers will direct traffic through the construction zone from 7 p.m. to 5 a.m. Traffic will be restricted to one lane at various times during the night. Restrictions will be in place Sunday through Thursday for each of the next three weeks. During the day, construction will be limited to the shoulder and side of the roadway and will not restrict traffic.

From spring through early summer, crews will work on the second phase of improvements, which include widening and rebuilding the north side of Idaho 44 from Linder to Ballantyne and rebuilding the east side of the Linder Road intersection. A traffic switch is planned for July 1.

The contractor is working on the north side of Idaho 44, and plans to start paving Monday (June 17). Crews also are working on the west side of Linder Road.

The project is expected to be complete by this fall.

Central Paving, of Boise, is the contractor on this $9.23 million project.

ADAMS, WASHINGTON COUNTY
U.S. 95 resurfacing Manns Creek to Alpine Store

Sections of U.S. 95 totaling 31.1 miles, from Manns Creek to Shoepeg Road and Cambridge to the Alpine Store, will be resurfaced in a project this summer to extend the life of the road and improve traction for drivers.

The resurfacing will take place starting Monday (June 17), from milepost 87.5 to 108.9, and from 113.7 to 123.4. The route travels through Washington and Adams counties. Work is expected to finish by late August.

The work is part overlay and part CRABS (Cement Recycled Asphalt Base Stabilization). CRABS is an in-depth resurfacing method. The existing roadway is pulverized down to the gravel base, cement is added to the pulverized material, and finally a new layer of asphalt pavement is placed on top.

More than 6,000 feet of guardrail will be replaced to meet current standards. The project also will include some improvements to bridge decks and the current drainage systems at Monroe Creek (milepost 88.3) on the southern end of the project area and 18 miles farther north at Keithly Creek (milepost 106.5).

Knife River Corp. Northwest, of Boise, is the contractor on this $6 million project.

BOISE COUNTY
Idaho 21 resurfacing to Lowman

A resurfacing project covering 20.4 miles of Idaho 21 in Boise County has wrapped up for this construction season. Work will resume in mid-July, as consistently hot temperatures are required for the remaining resurfacing.

The project runs from Mores Creek Summit to Clear Creek Bridge below Lowman, adding a Stress-Absorbing Fiberglass Layer with Emulsified Asphalt (SAFLEA) on two adjoining sections of Idaho 21 (milepost 52.3 to 60 and 60 to 72.7), conducting slope stabilization, and upgrading guardrail at existing locations.

A SAFLEA treatment, which will be added next summer, is a seal coat with a coating of chopped glass fibers between the oil and gravel aggregates to enhance durability and reduce cracking.

Knife River Corp, of Boise, is the contractor on this $3.9 million project.

BOISE COUNTY
Idaho 55 resurfacing from Horseshoe Bend north to bridge

A resurfacing project on Idaho 55 from the Payette River Bridge on the south end of Horseshoe Bend to the Payette River Bridge north of town started Monday (June 10). The project should take approximately four weeks to finish.

Work will be done from 8 p.m. to 7 a.m.  Traffic will have two travel lanes during the day. During work hours, traffic will be controlled with flaggers and, in some cases, a pilot car.

Crews also will repair soft spots in the highway before paving. The resurfacing covers a little more than two-and-one-half miles, from milepost 63.67 to 66.  

Portions of the project that cannot maintain two open lanes and a work zone, at the north and south ends, will be completed at night.

This week, crews repaired deteriorated sections of pavement and upgraded the drainage at the junction of Idaho 55 and Idaho 52. Next week, they will begin the thin-lift overlay. Two lanes are maintained through daytime hours although there is some work on the shoulder. From 8 p.m. to 6 a.m. Monday through Thursday, there will be lane restrictions, with flaggers and possibly a pilot car.

C & A Paving, of Boise, is the prime contractor on this $618,000 project.

BOISE COUNTY
GARDEN VALLEY - South Fork Payette River Bridge

This is a bridge-replacement of the old bridge over the south fork of the Payette River near Garden Valley. The old bridge, located southwest of town, also called the Alder Creek Bridge or Silver Bridge, has a sufficiency rating of less than 50. Boise County is the local sponsor. The new bridge will be relocated upstream and the existing bridge will serve as a detour during construction.

ITD provided no input on the design phase of this project. Two open houses were held - on April 26, 2007, and March 2, 2011. In May 2011, J-U-B Engineers and Langdon Group staff met on-site with impacted property owners to survey and discuss right-of-way staking. River rafting companies and emergency responders were also contacted by phone and email in early summer 2011. Twenty-six people signed in at a public hearing on Jan. 9, 2012.

Ralph L. Wadsworth Construction Company Inc., of Draper, Utah, is the contractor on this $2.3 million project.

Construction is scheduled to begin later this summer. This is an LHTAC (Local Highway Technical Assistance Council) project. ITD has oversight responsibility for this work.

CANYON COUNTY
CALDWELL – I-84 Business Loop

A section of the I-84 Business Loop in Caldwell is scheduled to be resurfaced starting Monday (June 17). Three segments will be impacted – Cleveland Boulevard, Centennial Way and Blaine Street.

The project also will address 44 ramps to make them compliant with the Americans with Disabilities Act.

Crews are planning to work a 7 a.m. to 7 p.m. schedule Monday through Friday. Weekend work is not anticipated, but is not prohibited if necessary.

One lane of traffic will remain open during the work. Flaggers will be used on cross streets during milling and paving operations and to move equipment in and out of the work area. No pilot cars or temporary signals are expected.

The westbound off-ramp will be closed for about a week as crews complete work there.  A detour will be announced during that portion of the project.

C & A Paving Co., of Boise, is the contractor on this $1.2 million project. 

OWYHEE COUNTY
MURPHY – Idaho 78, Scorpion Creek Bridge

A project to place a bridge over Scorpion Creek on Idaho 78 in Owyhee County continues. The south side of the bridge will be built first, then the north side.

The new concrete slab bridge will replace three corrugated-metal culverts that run under the roadway at milepost 23. One culvert is completely plugged. The other two culverts are more than halfway filled with sediment from the creek. Water runs over the highway at that location during periods of high water, creating a safety hazard.

The new bridge addresses a safety concern with water spilling over the roadway every time Scorpion Creek floods, which is nearly an annual event. The new bridge, about six miles northwest of Murphy, will accommodate higher water levels. The roadway elevation also will be raised about two feet. The roadway approaches will be reconstructed to match the new height and the wider bridge.

No night or weekend work is anticipated but is not prohibited, if necessary, to finish the project on time.
One lane of traffic will be maintained across the bridge during construction, controlled by a temporary traffic signal. Flaggers will be used when needed.

The existing culverts will be removed as needed to build the new bridge while still allowing for water flow.

Issues with bearing pads may slightly delay the placement of bridge girders.

Knife River Corp. Northwest, of Boise, is the contractor on this $947,000 project.

PAYETTE COUNTY
FRUITLAND - SW 3rd Street; Iowa Avenue to Jct. U.S. 95   

This Local Highway Technical Assistance Council (LHTAC) project is a reconstruction of the main street through old downtown. The pavement is old and excessively patched, sidewalks are deficient and there are drainage issues.

Construction began in mid-March. Crews have completed Phase 1, and Phase 2 is under way. Phase 2 should conclude in early August. The job is on schedule to finish in early October.

The city of Fruitland is the local sponsor.

Irvco Asphalt & Gravel, of Fruitland, is the contractor on this $2.25 million project.

VALLEY COUNTY
CASCADE – Bridge Replacement

Replacement of the North Fork Payette River Bridge in downtown Cascade continues. The bridgework will extend into late fall 2013.

This project will replace the old, narrow, width-restricted bridge built in 1933 with one more than twice as wide. The existing bridge is 24 feet wide, and will be replaced with a 60-foot wide, 393-foot long, three-span bridge. The new bridge will have two 12-foot lanes, two 11-foot shoulders and a 14-foot median.

In addition, a paved extension will be built to the dirt shared-use path under the bridge on the north side of the river that provides access from both sides of the bridge to the new riverside park. The short section under the west half of the new bridge has been graded, but has not yet been paved. 

In the first stage, two-thirds of the new bridge will be built to the west of the existing structure. Traffic will be maintained on the existing bridge through this first stage of bridge work, and then will be routed to the new section of bridge for the remaining work as the old bridge is demolished. There will be traffic interruptions while the new roadway section leading to the new bridge is built.

From Monday through Thursday, work that limits drivers to one lane in each direction is only allowed between 9 a.m. and 4 p.m. Two lanes will be maintained between noon Friday and noon Monday. A river safety and navigation plan will be in place for recreationists that use this section of the river.

Crews switched traffic to Phase 1 of the new bridge and began demolition of the old structure.

Wadsworth Brothers Construction Co. Inc., of Draper, Utah, is the contractor on this $4.83 million project.

VALLEY COUNTY
CASCADE - Lakeshore Drive reconstruction

This upcoming project involves reconstructing and widening 1,400 feet of roadway from old State Highway Road to Caddy Lane utilizing city-owned right of way, as well as replacing sewer and water system utilities and adding a sidewalk on the east side. The total project will cover the area from Dam Road to Duffers Lane, approximately 1.15 miles.

Public Lands Highway Discretionary Program and City of Cascade funds are being used to build this project.

Granite Excavation, of Cascade, is the contractor on this $633,000 project. Construction is expected to start in late summer 2013.

WASHINGTON COUNTY
WEISER – replacement of bridge over Weiser River

The replacement of a 78-year-old bridge over the Weiser River south of Weiser has begun, with several significant traffic impacts. The work on U.S. 95 is expected to be done by the end of this year.

Traffic is restricted to one lane across the bridge. North- and southbound traffic will alternate across the bridge, controlled by temporary signals at both ends of the structure.

Drivers are reminded to use patience during reconstruction and perhaps consider an alternate route, such as Oregon State Route 201 and the U.S. 95 Spur.

Traffic volume increases on U.S. 95 on weekends, so electronic message boards, both on the side of the highway and overhead on westbound I-84, will be used to alert motorists of bridge restrictions. Crews plan to work Mondays through Fridays, but will be off the highway on weekends and holidays.

The two-lane bridge, one of 99 remaining on the state system built before 1936, will be replaced with a three-lane structure. The existing bridge has 26 feet of drivable width, but the new one will be expanded to 48. An average of 7,300 vehicles use the bridge daily. More than 100 million vehicle trips have been taken across the bridge during its lifetime.

In addition to replacing the aging bridge, crews also will reconstruct more than 500 feet of bridge approaches at the north and south ends.

The existing bridge has a sidewalk and two 13-foot lanes but no shoulders. The new bridge will have two 12-foot lanes and a 12-foot center turn lane. The project features a two-foot buffer next to the decorative bridge railing, a five-foot shoulder and a five-foot sidewalk on the west side. No bike lanes will be included in the project.

The new bridge will be 346 feet long and 55 feet wide, including the parapet.

The contractor has completed forming up and pouring concrete for the phase 1 bridge sidewalk. Crews also have removed the existing asphalt north and south of the bridge and have been placing base course. Over the next week, they will begin placing sections of  decorative guardrail on the bridge and placing asphalt at the north and south ends.

Braun-Jensen, of Payette, is the prime contractor on the $4.8 million project.

DISTRICTWIDE
Sign repair/replacement

Nearly 150 highway signs along southwest Idaho roads will be repaired as ITD performs annual sign repairs for the next several months. ITD is responsible for providing safe roads for Idaho motorists, which includes ensuring clear and understandable information by providing proper signage on roadways.

The signs to be repaired are located on Interstate 84 from the Oregon Border to just east of Mountain Home (milepost 0-121), on the Connector, U.S. 20/26 in Boise and on the U.S. 95 Spur in Fruitland.

Work began June 3. The signs in Boise will be done first. Signs at Franklin and then in Fruitland will follow, and then the project will return eastward.

Of the 149 sign locations to be upgraded, 73 sign locations are in need of total replacement of sign faces, posts and foundations. Another 76 will have new sign faces only.

Almost 26,000 square feet of signs will be repaired, with crews replacing damaged posts, replacing old sign bases with new break-safe sign bases, improving brackets and updating the reflectivity on sign panels where the paint has dulled.

Most of the work will be on the shoulder and will not require lane closures. All work that impacts traffic will be conducted overnight. No work will take place on the Connector during the evenings of home Boise State football games. Lane closures will be coordinated with special events if necessary. Work also will not be done during the Fourth of July holiday.

This work will be done under a contract, as the sheer volume of sign repairs would quickly overwhelm ITD’s five-man Sign Crew. Most of the signs are the original ones and have begun fading with age. ??The project is expected to finish by September.

Pavement Markings Northwest, of Boise, is the contractor on this $907,000 project.                    

Highway construction is one of the key forces pushing Idaho toward continued economic vitality by creating jobs, improving safety and reducing traffic congestion.
