What's happening on I-405 in Bellevue?
WSDOT is widening I-405 between 112th Avenue SE and SE Eighth Street. As part of the project crews will place test sections of asphalt quieter pavement on sections of northbound I-405. To place the test sections crews will need at least 70 degree temperatures and will also close three lanes on northbound I-405 between 112th Avenue SE and NE Sixth Street and ramps in the Bellevue area.
When will the lanes and ramps on northbound I-405 be closed?
Only one northbound lane will remain open on I-405 between 112th Avenue SE and NE Sixth Street from 5 a.m. Saturday, Aug. 15 to 5 a.m. on Monday morning, Aug. 17.
Saturday, Aug. 15 crews will also close:
- the carpool off-ramp to NE Sixth Street from northbound I-405.
Sunday, Aug. 16 crews will also close:
- The on-ramp from Coal Creek Parkway to northbound I-405.
- The off-ramps to east and westbound I-90 from northbound I-405.
- The off-ramp to SE Eighth Street from northbound I-405.
Crews will reopen all lanes and ramps by 5 a.m. on Monday, Aug 17.
