The West Phase of the Mercer Street corridor project in Seattle is under way and drivers trying to get from the Lower Queen Anne neighborhood to Interstate 5 can expect fewer lanes and longer delays for the next couple of years.
Here are the changes:
- Mercer St. will be reduced to two eastbound lanes between 4th Ave. N and 9th Ave. N.
- Local access will be maintained at Taylor Ave. N.
- The sidewalk on the north side of Mercer St. will be closed between 5th Ave. N and Dexter Ave. N. The sidewalk on the south side of Mercer St. will remain open.
- SR 99 traffic will be shifted to the west side of the roadway between Valley and Harrison streets. Two lanes of SR 99 in each direction will remain open.
- The northbound SR 99 off-ramp to Mercer St. will be permanently closed. A new signalized intersection at Republican St. and Dexter Ave. N will be available for northbound SR 99 traffic to reach South Lake Union.
- Broad Street is now open to two-way traffic.
SDOT said it will make signal modifications at 5th Avenue North and Harrison Street, as well as Harrison Street and Broad Street, in order to improve access to Broad Street.
