Bridge work to affect U.S. 95 traffic at White Bird Creek April 6-May 15
LEWISTON - Motorists traveling on U.S. 95, Idaho's primary north-south highway, will experience minor traffic delays this spring during the resurfacing of White Bird Creek Bridge south of Grangeville, the Idaho Transportation Department announced.
Work is expected to begin April 6 on the removal and replacement of 1.5 inches of the concrete bridge deck. The new surface will provide smoother travel and help protect the bridge deck.
One side of the bridge will be closed 24-hours a day during construction, beginning with the southbound lane. Flaggers will limit traffic to alternating one-way travel on the lane that remains open. After that southbound side is resurfaced, the process will be repeated on the northbound travel lane.
During construction, which is scheduled for 40 calendar days (April 6 through May 15), the speed limit will be reduced to 45 mph for passenger vehicles and northbound commercial trucks in the work zone. Southbound trucks traveling down the White Bird grade will be limited to 25 mph.
Minor delays of up to 15 minutes are possible.
For safety, all trucks southbound on U.S. 95 will be diverted to a turnout near milepost 231 at the top of the White Bird grade. Truck drivers will be advised by a flagger of work taking place at the bottom of the 7 percent grade and of the 25 mph speed limit. Truck drivers should be prepared to stop at anytime on the downgrade.
Truck drivers northbound from Riggins also should be aware of the traffic control at the bridge because they will not be able to carry their speed through the work zone and into the steep White Bird incline.
Westway Construction Inc. of Airway Heights, Wash., is the contractor for the $1 million project.
All motorists are urged to use extreme caution while driving through the work zone and to watch for construction vehicles and workers.
