March 2008

Crews have finished planting in much of the project area and are now planting inside the park and ride lot.

Crews pour the decks of the new bridges over I-5.

Next, crews will begin building the approaches to the bridges..
February 2008

With the new girders in place crews began building a temporary work platform between the girders.

Crews worked overnight on Feb. 2 to successfully set the final 16 girders of the project and were able to open the roadway ahead of schedule.

Crews set 16 bridge girders for the south half of the new 112th bridge over southbound I-5 on Saturday, Feb. 2.
January 2008

Crews use a crane to lift a bridge girder for the south half of the new 112th Street SE bridge into place over northbound I-5 in early January.
Fall 2007

Work continues in the park and ride lot. Here crews are pouring and finishing concrete for a slab in the middle of the lot.

Crews building supports for the south half of the new 112th Street SE bridge.

Crews pour concrete to form one of the footings for the new bridge supports.

In mid-September crews took advantage of dry weather to install the curbs and pave inside the park and ride lot in the I-5 median.

In September crews drilled and poured concrete for shafts to support the second half of the new 112th Street SE bridge over southbound I-5.

An aerial view of the project in September shows traffic on the north half of the new 112th Street SE bridge, the old bridge gone, and the ramp leading from 112th to the new park and ride in the median.

Another aerial view shows more of the park and ride area. Crews will pave the park and ride in mid to late September, before the risk of poor weather closes the paving window for the fall and winter.
Summer 2007

August 18-20 we demolished the old 112th Street SE bridge over southbound I-5.

In August crews removed the deck of the old 112th Street SE bridge before tearing down the girders.

In June crews accomplished a great deal of the construction of the ramp from the 112th Street SE bridges to the park and ride area. Solo drivers will access the park and ride using this ramp.

In June we poured concrete for the west bridge deck. We're installing barriers across the bridges and completing a long list of other work on the new bridges before we can switch traffic to them later this summer.

In May crews installed reinforcing steel for the 112th Street SE bridge deck over northbound I-5. We poured the concrete for the bridge deck in late May.

In May crews began building walls to support a new ramp that will lead from 112th Street SE down into the park and ride in the I-5 median.

Spring 2007

Early on Sunday, April 22 crews set girders for part of the new 112th Street SE bridge over southbound I-5. We completed the work in six hours and reopened southbound I-5 at 6 a.m.

In early spring crews work on foundations and supports for the 112th Street SE bridge over southbound I-5.

In the early morning hours of Sunday, March 11, crews set girders for a portion of the new 112th Street SE bridge over northbound I-5.
Fall 2006

Despite poor weather in December, crews continued building columns to support the new, wider 112th Street bridges over I-5.

Looking north at the I-5 median from 112th Street SE. This is the future site of Washington State's first park and ride in a freeway median.

Crews removing trees from the I-5 median where we will build the new park and ride.

Looking west on 112th Street SE at Silver Lake Road, just east of I-5. Before our project, 112th had only one lane in each direction over the freeway, with narrow sidewalks.
