(UPDATE, Thursday, Sept. 10) -- A public meeting will be held in Riggins Wednesday, Sept. 16, on the Race Creek Bridge replacement project.

The public information meeting will be held upstairs in the Riggins Community Center, at 121 Lodge Street. The meeting will begin at 1 p.m. Mountain time. The contractor will be on hand to answer questions.


State construction of turnbays and a bridge replacement project gearing up this week will cause some delays for motorists along U.S. Highway 95 into fall and winter.


Improving safety is driving turnbay construction at three intersections, which are set for completion in October: one mile north of Cottonwood at Greencreek Road, 10 miles north of Grangeville at Lake Road, and south of Riggins at Pollock and Fuzi roads.

According to the Idaho Transportation Department, crash rates, crash severity and turning data were all studied as part of moving these projects forward.

Crea Construction Inc., of Lewiston, is the contractor on the $215,000 project at Cottonwood and Grangeville that will widen the road to accommodate right-turn lanes at these locations. On the Riggins project, two left-turn bays and a right-turn lane will be added to the intersection by widening the existing roadway. Knife River Corporation Northwest, of Boise, is the contractor on this $589,000 project.

Motorists are asked to drive with caution in these areas, and delays up to 15 minutes may be possible through the Cottonwood and Grangeville projects.

Race Creek Bridge Project

Originally set to start Sept. 1 but delayed due to area wildfires, the $2.3 million Race Creek Bridge replacement project north of Riggins is now tentatively set to begin on Monday, Sept. 14.

“But we obviously don’t want to start it if there are still fire issues,” clarified ITD spokesman Steve Grant.

Work is expected to run through mid-February 2016 on replacing the existing 72-foot-long, 24-foot-wide concrete structure, built in 1932, with a 102-foot-long, 40-foot-wide pre-stressed concrete bridge, construct roadway approaches, and also replace nearly 1,500 feet of guardrail with concrete barrier.

Reason for replacement is the existing bridge is classified as functionally obsolete because it is too narrow.

Temporary traffic signals will control traffic at the construction area, between mileposts 196.6 and 196.9. Handling the contract is West Company Inc., of Airway Heights, Wash.
