Lake Washington

Crews poured the concrete foundation within the cofferdam for Pier 1 in Lake Washington. Over the next couple of weeks, crews will continue to assemble rebar for the pier columns. Later this month, a 200-foot tall tower crane will be installed within the cofferdam to assist with project activities.

On Pontoon W, crews continue activities to construct support columns and other structures. Two box columns enclose access stairwells for maintenance crews. The final concrete pours for these box columns was completed last week.

On March 15, crews finished installing the last anchor needed for the new floating bridge. A total of 58 anchors will secure the pontoons for the new floating bridge.

The location of the Pier 1 cofferdam and project barges completely block the east navigation channel. This obstruction alters use of the east navigational channel and SR 520 drawspan. Read more information for boaters and SR 520 drivers.

Medina

On land in Medina, crews have completed construction of Pier 3, the eastern-most pier. Crews have begun to prepare the pier for installation of the new roadway.

At Pier 2, crews are preparing to install the first new roadway for the new floating bridge. The roadway will be constructed on the top of the tall columns, which can be seen from the existing bridge.  

Kenmore

Construction of all anchors for the floating bridge is complete. Crews continue to construct pre-cast concrete panels for the bridge maintenance facility dock.

Construction of the new roadway deck section casting facility continues. Casting of the roadway deck sections is planned to begin in summer 2013.

Tacoma

Crews are currently constructing the next cycle of pontoons. In mid-March, crews began pouring concrete for the pontoon walls. During this cycle, crews will construct eight pontoons. 

The previous cycle of pontoons was completed earlier this year. Between Jan. 29-31, a total of six pontoons were towed out of the casting basin in Tacoma. Check out photos on our Tacoma Flickr page and watch the time-lapse video on YouTube.

Grays Harbor

Crews continue to construct the second cycle of six pontoons at the casting facility in Aberdeen. You can find more information on the Pontoon Construction Project on the project website.

The first cycle of pontoons floated out of the basin in July 2012. Check out our time-lapse video and photos of the work.
