7. U.S.-2, Dover Bridge replacement

Dover, Idaho
Start: Fall 2009 Finish: Fall 2011
Contractor: Sletten Construction
Contract: $23 million (ARRA-funded project)

The current bridge is a 295-ft trestle built during the 1930s and now the most restrictive bridge on U.S. 2 through Idaho. It will be replaced with a 72-ft-wide steel bridge. The highway will be realigned with improved access into the city of Dover.

Twin Falls County, Idaho
Start: Sept. 2009 Finish: Dec. 2010
Contractor: W.W. Clyde & Co.
Cost: $29.3 million (two projects)

Project Description: Stage II will connect with Stage I (completed in 2006) and continue west along Pole Line Road to 2400 East Road, then south to the U.S. 93/U.S. 30 junction. The first stage constructed four- and six-lane sections of the Twin Falls Alternate Route from Blue Lakes Boulevard to Grandview Drive. The flyover will provide a bypass option for traffic traveling past Twin Falls.

When complete, the Twin Falls Alternate Route will be a two-lane, limited-access road. The project includes construction of a four-lane, steel-girder bridge over Rock Creek Canyon. The flyover is a post-tensioned concrete girder bridge and will improve the safety of the Pole Line Road/Alternate Route intersection west of Twin Falls.
