Travelers heading north from westbound Roy Street will be detoured onto southbound  Queen Anne Avenue N and then right onto Mercer Street to proceed north on Second Avenue W. Travelers from Downtown should use First Avenue N to westbound Mercer Street and Second Avenue W or Fifth Avenue N and Taylor Avenue N to access Queen Anne.
  • Southbound Queen Anne Avenue N will be reduced to one lane between Valley and Roy streets. One lane of southbound traffic will be maintained at all times.
  • Access to Queen Anne Avenue N from eastbound Roy Street will be closed. Turns onto westbound Roy Street from southbound Queen Anne Avenue N will not be allowed. Uniformed Police Officers will be placed at the intersection of Roy Street and Queen Anne Avenue N to facilitate traffic flow.

Rescheduled: Two-way traffic on Mercer Street between First Avenue N and Fourth Avenue N; Roy Street restrictions begin the week of May 12

The previously announced two-way traffic conversion on Mercer Street between First Avenue N and Fifth Avenue N has been rescheduled for the week of May 12. Beginning next week, signal crews will begin converting intersections along Mercer Street to two-way traffic beginning at First Avenue N and working east towards Fourth Avenue N. The signal conversion process may take several days to complete and will likely begin towards the end of the week, weather permitting. As intersections are converted to two-way traffic, please pay attention to street signs as travelers adjust to new traffic patterns. The block between Fifth Avenue N and Fourth Avenue N will open to two-way traffic after construction at the intersection of Fifth Avenue N and Mercer Street the weekend of May 16-19. Please note the transition to two-way traffic is heavily dependent on weather. If inclement weather should occur, conversion dates may need to be altered.

Following the opening of two-way traffic on Mercer Street between First Avenue N and Fourth Avenue N, Phase II will begin which includes converting Roy Street between Queen Anne Avenue N and Fifth Avenue N to two-way traffic. During this conversion, westbound Roy Street will be reduced to one lane while final channelization is put into place. Signals will be activated for two-way traffic on Roy Street over a period of several days.

The final phase of converting Mercer Street to two-way traffic between Fifth Avenue N and Ninth Avenue N and closing Broad Street will likely occur immediately following Memorial Day in late May.
