FOR IMMEDIATE RELEASE

Southwest Idaho highway construction report for Nov. 30-Dec. 7

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

ADA COUNTY
BOISE - Idaho 16 Extension, Boise River Crossing

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 (Idaho 44) to Chinden Boulevard, including a new bridge over the Boise River.

Crews are finishing the highway embankment on the north half and building foundations and pier caps for the bridge.

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

ADA COUNTY
BOISE - Idaho 16 Extension, 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.

Concrete Placing is constructing the Phyllis Canal structure. Crews have placed the floors, abutments and are starting to work on the wing walls. Nampa Paving is working on placing the roadway base material from the Eureka Canal, north to the tie-in to the Boise River Bridge project. Crews have also started diverting the Eureka Canal to allow construction of the roadway base and three box culverts for Joplin Court Road and the Phyllis Canal access roads. 

Qualitree is removing trees from the right of way between Idaho 44 and Joplin Road. Knife River is working on irrigation facilities in that same location.

Substantial Completion is expected in December 2013, with overall completion in August 2014.

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

ADA COUNTY
MERIDIAN - Eagle Road resurfacing and medians

Work is wrapping up on this project, which is resurfacing Idaho 55 from Fairview Avenue in Meridian to State Street in Eagle, and installing raised medians from Franklin to Oakhampton Drive, one-half mile north of Chinden Boulevard. Crews began the work in early summer.

ITD activated a new traffic signal at Eagle Road and Chinden Boulevard Wednesday night (Nov. 28).

The intersection is being widened and reconfigured, the free-running right-turn in the southeast corner closed and the old signal poles were removed. 

Beginning Saturday morning (Dec. 1), ITD will open the new dedicated right-turn lanes at the southeast and northeast corners of the intersection.

All construction takes place at night and is weather dependent.

ITD is scheduled to complete the Eagle Road Construction project by mid-December.

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

ADA COUNTY
State St./Linder Rd./Ballantyne Lane intersection work

The project will ultimately reconstruct the intersection of Idaho 44 and Linder, including the reconstruction and expansion of Idaho 44 between Linder and Ballantyne and the rebuilding of Linder in the vicinity of Idaho 44.

Construction has begun. The first phase will be a temporary widening of the south side of Idaho 44 so traffic can move onto it and permanent road work can take place on the north side of Idaho 44.

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

ADA, BOISE COUNTY
Replacement of Dynamic Message Signs

In this project, DMS signs are being replaced in several locations, primarily on Idaho 21. The work involves removing the existing message signs and controller cabinets and replacing them with upgraded signs and cabinets at their current locations.

The sign locations are on Idaho 21 at the junction to Warm Springs, Idaho City, Lowman, and Stanley. And on the Banks to Lowman Highway at Banks, and Idaho 55 near the Shadow Valley Golf Course.

All work on this project is taking place on the shoulder and does not affect traffic.  Work will be suspended until late December early January.

Quality Electric Inc., of Boise, is the contractor on this $321,000 project. The work, which is not impacting traffic, is expected to finish by January 2013.

BOISE COUNTY
Idaho 21 resurfacing to Lowman

A resurfacing project covering 20.4 miles of Idaho 21 in Boise County is wrapping up for this construction season. The project is suspended until spring, and will finish in Oct. 2013. ITD crews are flushing culverts on Idaho 21 in the project area.

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.

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

CANYON, OWYHEE COUNTY
Idaho 55 resurfacing in Marsing, Caldwell

A resurfacing project is wrapping up at two locations between the Snake River Bridge in Marsing and Pride Lane in Huston, which is just to the west of Caldwell. The project extends 8.5 miles north from the bridge.

Work involves recycled asphalt and an overlay treatment. The two project locations are separated by just a few miles. Concurrent work on the bridge itself is taking place under a separate contract.

One lane of traffic will remain open, and motorists will be guided by flaggers on this two-lane road. The speed limit will be reduced to 35 mph in the work zone, and brief delays are expected. The delays should be 5-15 minutes typically, and up to 30 minutes if crews are working on the lower and upper sections at the same time and drivers get caught at both stops.

All paving is done. Crews are resetting guardrail and completing final tasks.

Knife River Corp. Northwest, of Boise, is the contractor on this $933,000 project.

CANYON, PAYETTE COUNTIES
I-84 median leveling, Black Canyon to Sand Hollow

The median of Interstate 84 near Sand Hollow, a few miles east of Black Canyon, is being leveled in a project expected to finish by the end of the month. Crews are removing the berms in the median of the interstate. The leveling is a safety improvement to minimize water runoff that created soft-spot hazards in the median.

The speed limit is reduced to 65 mph weekdays (during the day) between milepost 13 (Black Canyon) and 17 (Sand Hollow), and the inside (left) lanes will be coned off in each direction during the work.
The project is complete except for final installation of catch basins.

Irvco Asphalt & Gravel Inc., of Fruitland, is the contractor on this $235,000 work.

VALLEY COUNTY
CASCADE – Bridge Replacement

A replacement of the North Fork Payette River Bridge in downtown Cascade is now under way. The bridge work will extend into summer 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.

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.

This week, the contractor set another span of girders. Crews also are forming and setting rebar for the wing wall at Abutment 1. Crews will set the last Phase 1 span of girders on Tuesday (Dec. 4) and likely pour the wing wall.

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 continued economic vitality by creating jobs, improving safety and reducing traffic congestion.
