There are new changes, effective now, for driving through and around the construction of a new roundabout at Sharpes Corner.
Washington State Department of Transportation contractor crews from Tapani, Inc. is starting the largest stage of this project, building the double lane roundabout at the intersection of SR 20 and SR 20 Spur on Wednesday, May 30.
During this stage, crews will remove the stoplight and reduce traffic to and from Anacortes and Whidbey Island to a single free-flowing lane in all directions around the center work zone.
Here's what's happening:
- To Anacortes or the San Juan Islands from Interstate 5- Use a newly built bypass lane on the north edge of the intersection.
- To Whidbey Island from I-5- Crossover east of Sharpes Corner into an eastbound lane and through the intersection into the left lane climbing the hill toward Whidbey Island. People driving can choose either lane to go straight through the SR 20 and Miller Gibralter roads roundabout toward Whidbey Island.
- To I-5 from Whidbey Island- Travel through the new roundabout at SR 20 and Miller/Gibralter roads down the hill and curve right through the new bypass lane on the southeast side of the intersection.
- To I-5 from Anacortes/San Juan Islands- Turn right at SR 20 and head up the hill toward Whidbey Island. Drivers will merge into the left lane, make a U-turn at the new SR 20 and Miller Gibralter roads roundabout, drive down the hill and curve right through the new bypass lane on the southeast side of the intersection.
- To Anacortes from Whidbey Island- Travel through the new roundabout at SR 20 and Miller/Gibralter roads, down the hill and curve right through the new bypass lane on the southeast side of the intersection and U-turn at March’s Point/Christianson road.
What’s been done? Since starting work on Monday, April 2, crews have:
- Completed construction of a roundabout at SR 20 and Miller Gibralter roads.
- Added a climbing lane to westbound SR 20 between the two intersections.
- Built two new bypass lanes.
- Made storm water and drainage improvements.
- Installed guardrail.
- Improved electrical connections, including adding new lighting.
- Nearly finished work on a new bicycle and pedestrian trail.
In the final month of work, crews will open the Sharpes Corner roundabout as a single-lane roundabout by mid-June. It will be completed and in its final configuration as a double lane roundabout by early July. All lanes and the bicycle and pedestrian path will be open for use by Fourth of July travelers to the Anacortes, Whidbey Island and San Juan Islands areas.
