Coal Creek Parkway Culvert Replacement
Receive Alerts about updates with this project
Coal Creek Parkway has been repaved, and we are making great progress! Although all four lanes are now open, some lane closures will still occur periodically through October and perhaps early November during non-commute times while finishing work is completed by the city and private ranchise utilities. The project provides:
- A new bridge/culvert to support and keep safe Coal Creek Parkway, used daily by 28,000 motorists.
- A new pedestrian walkway under the bridge and stairs to connect Coal Creek Trail,
- Stream restoration to improve salmon passage,
- Landscaping to enhance the area.
Relocation of complex utilities under the parkway required the project to be done in two phases over a year and a half, and we appreciate your patience while this very important project moved forward.
HEADED TOWARD THE FINISH LINE.
Coal Creek Parkway has been paved and all four lanes are now open. There will be some lane closures during non-commute hours while the city completes the project and private utilities finish their work. Salmon have already been seen in the restored stream.
Bike Lane Changes
Bicyclists are encouraged to consider alternate routes during construction of the project, which can be found on the King County Bike Map. During October, bike lanes will be restored on both sides of the road.
Trailhead and Parking Lot Changes
Work on the Coal Creek trailhead and parking lot will continue through October and possibly early November.
Coal Creek Parkway carries nearly 28,000 cars a day, is an important route for Bellevue and regional commuters and provides a corridor for a number of utilities. Ensuring it is a safe and reliable transportation route is a priority for the city. The culvert under the street near Southeast 60th Street -- essentially a nine-foot wide corrugated metal pipe that is a conduit for Coal Creek -- was deteriorating and at risk for failure during heavy rains. Photos of aging culvert. The city had conducted a number of short-term repairs to the culvert, which extended its lifespan. However, engineering analysis of the culvert indicated that continued short-term repairs are no longer viable. As a result, Utilities designed a long-term solution, a 39-foot-long bridge over the stream.
The city is committed to keeping people informed about the project, both before and during construction.
