Mercer Street on-ramp to northbound Interstate 5 closing Friday to Monday
The Washington State Department of Transportation is closing the Mercer Street on-ramp to northbound Interstate 5 from Friday, Feb. 3 at 9 p.m. to Monday, Feb. 6 at 4 a.m. for construction.
This includes the express lanes entrance. There will be detours in place, WSDOT said.
The westbound State Route 520 off-ramp to southbound I-5 is reduced to one lane through at least Feb. 2023.
The closure is part of the SR 520 and I-5 Express Lanes Connection Project, which will create a dedicated reversible transit and carpool connection between SR 520 and the I-5 express lanes, along with a reversible transit and carpool ramp at the I-5 and Mercer Street interchange. The entire project is set to finish in 2024, according to WSDOT.
The project was started to create:
Safer and more reliable bus and carpool travel between the Eastside, South Lake Union area, and downtown Seattle.
Earlier than planned Eastside and South Lake Union transit service via the reversible I-5 express lanes connection.
A more efficient phasing of SR 520 construction that minimizes contractor overlap in the Montlake area and keeps traffic moving during construction.
