Aug 20, 2014: It's been a busy week. The entire existing structurally deficient bridge has been removed (except for the H-piles added to the structure in the 1980's), the streambed under the new bridge has been worked on, and the contractor has prepared for upcoming pile-driving activities.The pile-driving subcontractor began installing sheet pile this morning.

Once the Bailey bridge is removed, the contractor will begin demolishing the existing structurally deficient bridge.

Detours maps have been provided on our website. Starting Aug 11, crews will be working long hours and often on weekends until the new bridge is ready for traffic to cross.

July 8th, 2014: Today, county commissioners approved the temporary closure schedule for the L-4 Salmon Creek Bridge on Littlerock Road SW so that construction crews can rebuild the failing bridge.
