South Park Bridge Construction Keeps Moving Along

by on March 8, 2012

The contractor for the project, Kiewit-Massman, has completed the in-water construction work on time, given that the fish window (which started on August 1) ended on February 15. Did you know? 6,000 tons of contaminated sediment were excavated! If you’d like to see a summary of the caisson construction work during this period, please visit: http://www.kingcounty.gov/transportation/SouthParkBridge/ProjectUpdates.aspx

Now the contractor is moving to work on the main piers above the water, including formwork and rebar installation for the leveling slab, pouring the pier walls, and sinking the caisson to final tip elevation.

Starting on March 19, road improvements are coming to 14th Avenue S., S. Sullivan Street and Dallas Avenue S.  During this phase of the project, King County will be realigning 14th Avenue S. to connect it with the new bridge, and improving traffic safety by adding a four-way intersection at 14th and Dallas Avenues. See this informational flyer for more details about the road restrictions and the work to be done.
