CPC, with the Boise City Parks and Recreation Department and the Idaho Transportation Department, built a new phase of the Boise City Greenbelt between Garden City and Americana Boulevard on the south side of the Boise River.  This project was the last gap of Greenbelt to be constructed in the Boise City Limits and has given bicyclists and pedestrians a connection from Garden City to Boise on the south side of the river.

From Ann Morrison Park, the finished pathway goes underneath Americana Boulevard, follows the river under I-184, underneath Fairview Avenue and Main Street, and connects up to the Greenbelt at Joe’s Crab Shack in Garden City.  This improved the public’s connectivity and commuter opportunities between Garden City and Boise. Here CPC constructed new concrete greenbelt pathways, various retaining walls, and new access ramps to the Greenbelt at important commuting intersections.

Upper Malad Bridge Replacement Project, Gooding County, Idaho, 2015.

CPC replaced Idaho Power Company’s Upper Malad Bridge, which spans the Malad River approximately 3.5 miles north of Hagerman, Idaho, in Gooding County. This bridge provides access to IPC’s Upper Malad Power Plant. CPC used in-river demolition and construction to remove the old timber deck structure in order to build a new precast concrete girder bridge across the river.  This new bridge was designed to support increased traffic required to perform the Upper Malad Turbine Replacement project.

CPC replaced the outdated I-84 interchange at Meridian Road with a new Single-Point Urban Interchange.  This new interchange has only begun to do its job in reducing traffic congestion, improving safety, and creating a fourth lane for traffic on I-84.  This design uses one single traffic signal in the middle of the interchange to direct all lanes of traffic, which increases efficiency and improves traffic flow and vehicle movement.

Now that we are finished, there are three through lanes for traffic in each direction on Meridian Road, I-84 has been widened to four lanes in each direction underneath the interchange, there are dual left-turn lanes on Meridian Road for each I-84 on-ramp, and new sidewalks and bicycle lanes on Meridian Road improve conditions for pedestrians and bicyclists as well.

CPC, along with the Idaho Transportation Department and various subcontractors, replaced the I-84, Broadway Avenue Interchange in Boise, Idaho.  Like the Ten Mile, Meridian, and Vista interchanges, Broadway now has a Single-Point Urban Interchange (SPUI) at the I-84 exit.

Here, CPC built two new bridges, one for the Broadway Avenue Overpass and another over the Union Pacific Rail Road.  We also installed various interstate and ramp concrete paving, guardrail, retaining walls, and many other items that have given Boise an interchange that will serve traffic demands now and into the future.

CPC, in association with the Oregon Department of Transportation and other contractors, helped to rehabilitate a 13-mile stretch of Oregon’s Interstate 84 between Exit 246 and the Second Street under-crossing in La Grande at mile post 260.2.  As part of this project, CPC placed concrete in the outside lanes of the freeway and built a westbound truck climbing lane along the Spring Creek grade – a notorious bottleneck due to the slow speeds of commercial vehicles climbing the very steep 6% hill.  Replacing the previous asphalt traffic lanes with concrete have also allowed for 35 years or more of useful life of the road surface, which is a vast improvement over the 8 years asphalt usually lasts.

Hubbard Bridge #345

CPC replaced the Hubbard bridge over the New York Canal near Ten Mile Creak Road in Ada County, Idaho.  The new bridge is wider and higher than the old bridge and is designed and built in anticipation of further widening in the future.  This project was completed in April 2013.

 

Interstate 84 – North Fork Jacobsen Gulch

CPC worked with the Oregon Department of Transportation to repair and resurface 10-miles of Interstate 84 between the North Fork Jacobsen Gulch and the Idaho border.  This project, in Ontario, Oregon, consisted of three phases:  a silica fume overlay on the eastbound Malhuer River Bridge; several miles of paving on I-84; and repaving of an off-ramp from the interstate.

 

State Highway 16 & State Highway 44 Interchange

CPC performed much-needed bridge deck rehabilitation and guardrail replacement at this important junction of SH-16, SH-52, and SH-44.  All work took place in Ada and Gem counties.

 

Interstate 84, Ten Mile IC to Meridian IC Reconstruction

CPC played a critical role in this fast track project to reconstruct both east- and westbound lanes on heavily traveled Interstate 84 in Boise, Idaho. CPC was responsible for the concrete median barrier, the concrete paving, and modifying both overpass structures to accommodate added lanes of traffic. Modifications included excavation and a soil nail wall to allow for a traveling lane between the abutment and pier at the Meridian Road interchange. Other modifications included protection of the existing overpass piers at both Meridian and Ten Mile Roads.

In addition to the structural work, CPC paved approximately 143,000 square yards of Portland cement concrete pavement in two planned phases. CPC was responsible for the manufacture of 45,000 cubic yards of concrete as part of this project.

This work was an Idaho Transportation Department GARVEE-funded project. It has made a significant difference to local commuters from the west end of the Treasure Valley.

 

US Highway 2, Havre, Montana

CPC was the subcontractor responsible for 85,536 square meters of 230 mm plain doweled concrete pavement through the city limits of Havre along existing route US Highway 2.  The project involved reconstruction of approximately 2.4 miles of roadway and included 2 lanes in each direction with center turn lanes and shoulder parking.  The work has greatly improved travel for travelers to and from Canada along with motorists along Montana’s Hi-Line (as US-2 is called by the locals).
