FOR IMMEDIATE RELEASE

Southwest Idaho highway construction report for Sept. 14-21

BOISE - The following projects in southwest Idaho are now under way.

ADA COUNTY
BOISE - Idaho 16 Extension

Work is under way for the first phase of the extension of Idaho 16, which will be complete in August 2014.

Crews will connect State Street to Chinden Boulevard, including a new bridge over the Boise River.

Crews are driving piles and placing leveling slabs for piers on the north side of the river, while also building access roads and irrigation for the south side.

Concrete Placing Co. Inc., of Boise, is the contractor on this $19.4 million project.

ADA COUNTY
BOISE - Idaho 16, Phyllis Canal Bridge and South Segment

This project extends Idaho 16 from U.S. 20/26 (at McDermott Road) to Joplin Road, where it ties in to the new Idaho 16 Boise River Bridge project.

The contractor has a 14-day waiting period required by the EPA before any ground-disturbing activities can take place.

Work is expected to begin soon on the first phase of the project, to demolish two houses (already abandoned and cleared) that are in the way of the new roadway alignment. One is on Joplin Road and the other is on Idaho 16, about one-quarter mile north of the Idaho 16/44 intersection.

Almost all work will be restricted to daylight hours, with the exception of activities like hauling bridge girders. 

The overall completion date is in August 2014.

Concrete Placing Co Inc. is the contractor on this $10.8 million project.

ADA COUNTY
BOISE – Connector resurfacing

A preventative maintenance project began July 29 on the Connector (I-184) in Boise, heading westbound. Work is expected to be finished by the end of this month.

For about five miles, from the Flying Wye to 13th Street, crews are re-sealing joints and grinding off the concrete surface to increase skid resistance.

Crews will adhere to a 10 p.m.-to-5 a.m. schedule, working overnight in order to minimize traffic interference.

Crews should completely finish both westbound and eastbound grinding this week. All work on the outbound (westbound) Connector should be done by the end of the week. The job should be completely finishedc in one or two weeks.

Work will not be allowed on the nights of Boise State University home football games.

A temporary closure of the ramps will be necessary for the contractor to properly grind and re-seal in those areas.

The speed limit will be reduced to 45 mph in the construction zone. 

Penhall Corporation, of Anaheim, Calif., is the contractor on this $919, 000 project.

ADA COUNTY
MERIDIAN - Eagle Road resurfacing and medians

Work started June 10 on this project, which will resurface Idaho 55 from Fairview Avenue in Meridian to State Street in Eagle, and install raised medians from Franklin to Oakhampton Drive, one-half mile north of Chinden Boulevard.

One northbound lane on Eagle Road from River Valley Street to Hobble Creek will be closed at night so crews can pave the roadway.

Between 9 p.m. and 5 a.m. one lane will remain open in each direction.

• At nighttime only, access will be limited to neighborhoods and businesses along Eagle Road between River Valley Street and Hobble Creek.
• There will be approximately 15-minute delays at both the Ustick Road and McMillan Road intersections.
• Please use alternate routes to avoid Eagle Road during the nighttime lane closures if you live in the area.
• Flaggers will direct traffic and help drivers find alternate routes to their homes and businesses.

Crews will finish paving the northbound section of Eagle Road by Sept. 18.

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

ADA, ELMORE COUNTY
Repair of seven bridge decks in Ada and Elmore counties

The repair and resurfacing of bridge decks on seven bridges from Boise through Mountain Home and to the east is nearing completion.

The contractor has completing all work on the Canyon Creek overpass at milepost 92, 18th Street overpass at milepost 94, Hwy 95 Interchange at U.S. 20, the Oregon Trail Interchange at milepost 99, and Hammett Interchange at milepost 112.

The Mayfield Interchange bridge at milepost 71 on I-84 will be closed overnight to allow the bridge deck to be jacked up and shimmed. While jacking the superstructure, I-84 will be reduced to a single lane and traffic diverted around using the on- and off-ramps. Flaggers will be used to assure smooth traffic flow.

The superstructure will be shimmed up, (approximately three-quarters inch) for up to a week to allow repair work on the substructure.

This structure will require some nighttime bridge closures for jacking the superstructure up to replace bearing pads and repairs to pier caps and girders, followed later with traffic reduced to a single lane and temporary signals to resurface the deck and replace joints.

Crews are also doing one of the bridge rehabilitation projects for ITD’s Caldwell office. The hydro-demolition equipment needed has been used at various other locations statewide, so current scheduling shows an expected completion date of mid-November.

Concrete Placing Co. Inc., of Boise, is the apparent low bidder on the $1.72 million repairs.

ADAMS, IDAHO COUNTY
U.S. 95 resurfacing Smokey Boulder – Hazard Creek

A five-and-a half-mile (milepost 171-176.5) pavement rehabilitation project on a stretch of U.S. 95 that wanders through Adams and Idaho counties as it heads north is under way.

One open lane will be maintained from Smokey Boulder Road to Hazard Creek during the two-month-long project. Flaggers and traffic cones will be used to guide motorists.

Pilot cars will guide traffic during surface pulverization and paving, set to begin this week.

Valley Paving & Asphalt Inc., of Cottonwood, Idaho, is the contractor on this $1.8 million project.

BOISE COUNTY
BANKS – Resurfacing

A 10.4-mile resurfacing project on Idaho 55 north of Banks from milepost 80.6 to the Boise National Forest boundary (milepost 91) is wrapping up.

Most of the work is complete. A few minor items remain.

Valley Paving & Asphalt Inc., of Cottonwood, Idaho, is the contractor on this $2.15 million project.

BOISE COUNTY
Idaho 21 resurfacing to Lowman

A resurfacing project covering 20.4 miles of Idaho 21 in Boise County is now under way and will finish by early fall 2013.

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 is a seal coat with a coating of chopped glass fibers between the oil and gravel aggregates to enhance durability and reduce cracking.

One lane of travel will remain open, with flaggers and pilot cars helping to guide traffic. Crews will work a 7 a.m. to 5 p.m. schedule Monday-Thursday and will work half days on Fridays. No work is allowed on the weekends.

The contractor continues installing trench drains and has reduced two highway lanes to one, with traffic controlled by flaggers.

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

CANYON, PAYETTE COUNTIES
I-84 bridge repairs

A project rehabilitating three bridge decks in the Caldwell area at Centennial Way, Exit 27 and the Boise River crossing, and the bridge deck at Exit 13 at Black Canyon, is under way.

Some ramps and lanes will be closed during the work. Crews will cone off the affected areas.

I-84, Exit 27 in Caldwell - remaining work on finger expansion joints.

I-84, Exit 13 at Black Canyon - current work is estimated to finish Sept. 21.

Concrete Placing Co. Inc., of Boise, is the contractor on this $1.42 million project, which is expected to finish by late October.

OWYHEE COUNTY
NEAR GRASMERE – Idaho 51 resurfacing

Resurfacing work is wrapping up on a 14-mile stretch of Idaho 51 through Owyhee County.

The remaining work is the second application of pavement markings. It will take one-half day and will be a mobile operation. ITD expects completion by Wednesday (Sept. 19).

Snake River Construction, of Twin Falls, is the prime contractor on this $1.6 million project.

PAYETTE COUNTY
PAYETTE – U.S. 95, Payette River Bridge replacement

The project to improve the U.S. 95 bridge over the Payette River south of Payette is wrapping up. It is expected to finish by the end of September.

Crews are replacing the existing northbound truss bridge (built in 1927) located on U.S. 95 between Fruitland and Payette.

The new bridge is two feet higher off the water. It has no overhead bracing or struts, as the current one does, and is 84 feet in width, eliminating current safety concerns regarding both width and height restrictions.

The new bridge is attached to the existing southbound bridge. The project also includes minor roadway realignment to tie into the new bridge location.

U.S. 95 is the main route connecting northern and southern Idaho. About 18,000 vehicles use this portion of the highway daily. By 2026, the volume is expected to be more than 25,000.

JC Constructors Inc., of Meridian, is the contractor for this $6.17 million project.

VALLEY COUNTY
CASCADE – Bridge and Roadwork

A replacement of the North Fork Payette River Bridge in downtown Cascade is now under way, with two miles of pavement resurfacing on Idaho 55 in town wrapping up. The roadwork is expected to finish soon, while the bridge work will extend into summer 2013.

ROADWORK:
This work is not yet completely done. Signs still need to be installed and there are punch-list items to finish. The signs are on backorder for about three more weeks.

C & A Paving, of Boise, is the contractor on this $1.86 million project.

BRIDGE WORK:
This one-year project will begin that will eventually replace the old (built in 1933), narrow, width-restricted bridge 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 constructed 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.??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.

A 12-foot width is in effect.

This week, the contractor built a crane pad in the river and erected the crane. Driving test pile on abutment 2 has also started. The new sewer line was installed and crews continued work on the new water line. The road crew continues work on the new alignment south of the bridge. 

Next week, pipe- and roadwork will continue and crews intend to drive the 36-inch pile at piers 1 and 2. Traffic interruptions will be minimal.

Flaggers will be used if lane restrictions are required. 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.

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

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