L-4 Bridge Construction Set to Start in August
Bridge will close for first phase of construction

Thurston County Public Works staff announced at their open house meeting yesterday that they are on track to begin the construction of the new L-4 Salmon Creek Bridge in August, and that the new bridge should be complete and ready for traffic by the end of the year.

Staff engineers have completed the design of the new bridge, and the construction contract is currently open for bid. Public Works staffers expect to select the contractor and finalize the construction plan in June and July. The first phase of construction, which includes closing the temporary bridge to make room for demolition and installing the new piers, is expected to begin in early August. The first construction phase is expected to take up to eight weeks, and all vehicles will need to use the detour route during that period.

"We explored nearly every option under the sun to minimize the amount of time that the bridge is closed," said Public Works Director Donavan Willcutt. "The plan we have now is the one that really minimizes the closure while still getting the project done right and getting it done this year. We know it's a real inconvenience for area residents, but at the end of this process, they're going to have a brand new bridge that is first and foremost a safe bridge for everyone."

Once the first phase of construction is complete and a temporary bridge deck is installed, passenger vehicles will be able to cross the bridge using a single lane that will alternate direction. School buses and emergency vehicles will also be able to use the temporary lane while construction crews continue working on the permanent bridge. Heavy trucks will continue to use the detour until the permanent new bridge is opened to all traffic.

The L-4 Salmon Creek Bridge on Littlerock Road SW located between 110th Avenue SW and 93rd Avenue SW was first closed on Monday, January 27 after structural deficiencies were discovered. In March, a modular temporary bridge structure called a Bailey bridge was installed at the L-4 Bridge crossing on Littlerock Road SW. With the help of crews from the Washington State Department of Transportation, the Bailey bridge opened Saturday, March 22 and has allowed passenger vehicles, buses and emergency vehicles to travel northbound and southbound using a single alternating lane. Heavy trucks continue to use the detour route.
