SR 28 - 5th Street Intersection Improvements


May 2017

This roundabout project is being advertised for private contractor bidding this month with construction later this summer.

Check this Roundabout page for how they work.

This (I-2) Highway Capital Improvement Safety Collision Reduction Project addresses a high collision location between the east end of the SR 285 Senator George Sellar Bridge and the Wenatchee Valley Mall in East Wenatchee.

Construction of a roundabout is currently scheduled to start in  2017 at the intersection of SR 28 and 5th St. NE (MP 4.25-4.45B) as well as to the westbound on-ramps to the bridge from 5th St. and from southbound SR 28 (Sunset Hwy.)

Why is WSDOT working to improve this intersection?
This area has been identified as a location in need of safety improvements due to the type, frequency and severity of collisions that happen here.

Washington State Patrol records show from October 2010 through October 2015 there were 30 collisions, with 10 resulting in injuries. During that same 5 year period for the SR 28 ramp onto the bridge there were another 38 collisions with 9 injuries. We are hosting an open house to share the alternatives we’ve considered and get feedback from the community on possible solutions.

The current east leg of 5th Street has a stop sign at the intersection. An estimated average of 4,850 cars currently (and a forecasted average of 7,200 cars in 20 years) go straight onto the George Sellar Bridge or turn right onto SR 28 daily from this east leg of 5th street. Traffic often backs up to Valley Mall Parkway and traffic trying to cross SR 28 cause a high percentage of T-bone and side collisions. The west leg of 5th Street has a yield sign for drivers to yield to traffic coming from the southbound SR 28 ramp to the George Sellar Bridge. The collision types there are mainly sideswipes as well as rear-end collisions.

The End Result
All current improvement options for this intersection are designed to significantly reduce the severity and frequency of collisions. The roundabout all but eliminates the possibility of the T-bone collisions that frequently occur at this intersection.

Project Benefits
The project is planned to reduce the number and severity of collisions at this intersection.

The roundabout will allow traffic heading south a new left turn movement to get to Valley Mall Parkway. This would also allow traffic an exit to Valley Mall Parkway if traffic is stopped on the Senator George Sellar Bridge.

In addition, a roundabout would likely help the mobility of westbound traffic on 5th Street to get onto the bridge.

What is the project timeline?
Advertised for bids in May.
Construction will begin later this summer.
Completion expected in late fall.
