L-4 Bridge Construction Contractor Selected
Active Construction of Puyallup awarded $1.6 million contract

Thurston County Commissioners today awarded a $1.6 million dollar contract for construction of the new L-4 Salmon Creek Bridge to Active Construction, Inc., which is based in Puyallup. The L-4 Salmon Creek Bridge project is on track to begin construction mid-July—a few weeks earlier than originally expected.

"We got a good response on this project and received a number of competitive bids," said Public Works Director Donavan Willcutt. "We have good momentum going on this project so far, and we're looking forward to working with Active Construction on developing a plan that keeps the bridge closure to a minimum, and that keeps us on schedule and on budget."

The L-4 Salmon Creek Bridge will be closed during a portion of the construction. The temporary Bailey bridge currently in place on the L-4 Salmon Creek crossing will be removed sometime in August to make room for demolition of the old bridge and construction of the new piers. This phase of the construction is expected to take up to eight weeks, and all vehicles will need to use the detour route during that period.

Public Works staff also announced today that they were able to work with the contractor on a construction plan that will allow all vehicles to use the bridge when it re-opens to traffic. The construction plan originally called for a single lane of alternating traffic that would be used only by passenger vehicles, school buses and emergency vehicles. The new plan allows for two lanes that all vehicles will be able to use, including heavy trucks. After the bridge re-opens to traffic, crews will continue to work on the new structure, and the new bridge should be complete by the end of the year.

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.
