Timber Way to Big Wood River Bridge
Project: Timber Way to Big Wood River Bridge
Project No.: STP-2390(138)
Key No.: 07836
The Timber Way to Big Wood River Bridge is the first phase of the Timmerman to Ketchum Corridor to be designed and constructed as directed in the Final Environmental Impact Statement. The project limits begin where Timber Way intersects with Idaho 75 (approximately .25 mile north of East Fork Road) and terminates 600 feet south of the Big Wood River Bridge near Hospital Drive.
The Idaho 75 Timmerman to Ketchum project includes the highway corridor from Timmerman Junction (US-20 and SH-75 intersection) north to the City of Ketchum. The Final Environmental Impact Statement and Record of Decision were approved in 2008 and included recommendations for project activities and project phasing. Additional phases of corridor improvements will be designed and constructed as funding becomes available.
The planned improvements to the Timber Way to Big Wood River Bridge project include widening Idaho 75 to two lanes in each direction with intermittent center turn lane for access to residences and businesses. Other improvements will include widened shoulders to 8 ft., deceleration lanes at Gimlet, Cold Springs and Broadway Run South intersections and drainage control facilities. The signal at the intersection with Hospital Drive will also be improved.
The design elements of the Timber Way to Big Wood River Bridge project are based on the Idaho 75 EIS concept plans. Construction begins in early May with construction of temporary roadway widening, the signal at Hospital Drive and retaining walls. Construction of the south-bound lanes is expected to begin in mid-June followed by the north-bound lanes in early August. The contractor anticipates completion in October but delays could extend work into 2014.
