News of Madison Valley

In a few weeks, WSDOT will open the new off-ramps from the brand new West Approach Bridge North. This will be the very first time westbound drivers travel on the new structure and use the new off-ramps to Montlake Boulevard and Lake Washington Boulevard. 

The new off-ramps are scheduled to open mid-July and the new westbound lanes from the floating bridge to Montlake are scheduled to open in late August. 

The opening of the new WABN bridge structure will take place in phases so that crews can remove the existing ramps to make space for the mainline construction.

As we get closer to this change, we will send more detailed information with graphics, videos, weekend work impacts and the specific date of the off-ramp opening. Be sure to stay in the loop by reading these email updates, following us on twitter, visiting our website and joining us for our regular, public meeting on Wednesday, July 12, at the Graham Visitor Center at 5:30 p.m.

Here’s a sneak peek at what to expect when the exit lane and off-ramps open:

• A westbound SR 520 closure from 11 p.m. Friday to 5 a.m. Monday the weekend before the westbound off-ramps open.
• Round-the-clock work during the westbound SR 520 closure. 
• An earlier exit for the new westbound SR 520 off-ramps, closer to the western end of the floating bridge (before the sentinel).
• Continued construction access via the 24th Avenue East bridge as crews use the MOHAI staging area through the end of the project.
