CENTRALIA – Next week, crews widening Interstate 5 in Centralia will reach a major milestone when they set 30 concrete girders alongside the highway.

The girders form the backbone of two new bridges that will eventually carry collector-distributor (CD) lanes over the Skookumchuck River. CD lanes help improve safety and mobility by eliminating merges between local and interstate traffic.

During the girder settings, I-5 drivers can expect lane closures from 7 p.m. to 6 a.m. Monday, Dec. 10, through Friday, Dec. 14.

Once all 30 girders are set, crews will build the skeleton of the bridge deck using wooden forms and rebar. The Washington State Department of Transportation expects to pour concrete for the new bridge decks in February. The CD bridges are scheduled for completion in May 2013.

The CD bridges are just one element in the first stage of the $155 million, gas tax-funded I-5, Mellen Street to Blakeslee Junction project.

Though the CD bridges will be complete next spring, the rest of the nearly mile-long CD lanes won’t be finished until the second stage of construction, set to begin in summer 2013. The entire project is scheduled for completion in early 2015.
