FOR IMMEDIATE RELEASE

Southwest Idaho highway construction report for Feb. 22-March 1

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

ADA COUNTY
BOISE - Idaho 16 Extension, Boise River Crossing plus Phyllis Canal Bridge replacement and South Segment (GARVEE)

Work is under way on the extension of Idaho 16, which will be complete in late summer 2014. Crews will connect State Street (Idaho 44) to Chinden Boulevard, including a new 1,726-foot bridge over the Boise River. Idaho 16 is also being extended from U.S. 20/26 (at McDermott Road) to Joplin Road, where it ties in to the new Idaho 16 Boise River Bridge project.

Crews are constructing box culverts in the Little Pioneer Irrigation Canal for what will eventually be S. Moyle Avenue. and S. Nightshade Place. They are installing girder stops and bearing pads for several piers, working on the wing walls and curtain walls for abutments, and removing materials and equipment from the river floodway in preparation for the upcoming runoff season.

Crews are installing irrigation, culver pipe and irrigation boxes north of Idaho 44 and south of U.S. 20/26 to ensure proper irrigation flow.

Crews are also constructing backfill behind several of the abutments for the bridge over Joplin Court Road and the Eureka Canal. They also will be preparing for the deck of the Phyllis Canal Bridge this week and next week. They will remove all materials and clean up the Phyllis Canal to get it ready for irrigation water. They are compacting the excavated areas and are importing granular base material to stabilize the new roadbed before spring rains come.

Concrete Placing Co. Inc., of Boise, is the contractor for both the first segment, which is the $19.4 million construction of the river crossing, as well as for the second segment, which includes the $10.8 million work to the south and a crossing of the Phyllis Canal Bridge.

ADA COUNTY
MERIDIAN - Eagle Road resurfacing and medians

Work is in winter shut-down mode on this project, which 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. Crews began the work in early summer.

A new signal is being designed that will be added in the spring at Wainwright Street and Eagle Road. Crews hope to begin that work soon, possibly in late March.

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

Traffic is restricted at night on Idaho 44 from W. State Street to just east of the Idaho 44/Linder Road intersection. ITD is replacing irrigation pipes under the roadway.

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. Construction is expected to be completed by this fall.

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.

The contractor is finished with the retaining wall, and is close to being finished with the two structures in the Middleton Mill Canal and South Middleton Mill canal. The design is nearly complete.

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. The upgrade involves the ability to activate the signs remotely, rather than having to go to each site to change the message.

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

The signs are in the 30-day test period to finish March 6.

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 has been suspended for the winter. Work will resume after June 15, 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.

VALLEY COUNTY
CASCADE – Bridge Replacement

A replacement of the North Fork Payette River Bridge in downtown Cascade is now shut down for the winter, but is expected to begin again in early March. The bridgework will extend into late fall 2013.

This summer also saw resurfacing of the roadway between the bridges in town.

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.??

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.
