SEATTLE — The Seattle Department of Transportation wants drivers to be prepared.

Broad Street permanently closed to traffic between 9th Avenue North and 5th Avenue North on Sunday.

The change allows Mercer Street to open to two-way traffic for the first time — connecting I-5 with Lower Queen Anne.

SDOT warns this will cause “significant traffic disruptions” along the Mercer Corridor.

Drivers are encouraged to use alternate routes and expect lengthy delays as drivers adjust to two-way traffic on Mercer Street.

“The closed portion of Broad Street will be used to widen Mercer Street in its final configuration of three lanes in each direction between I-5 and Fifth Avenue N and for the SR 99 North Access Project which will build connections onto adjacent surface streets from the future SR 99 bored tunnel,” according to a news release from SDOT.

Here’s a summary of the changes starting Monday, June 2nd:

  • Mercer Street will have two lanes in each direction between Queen Anne Avenue N and Ninth Avenue N.
  • Access to Seattle Center and Queen Anne will be a direct route via westbound Mercer Street from I-5.
  • Roy Street will have one lane in each direction between Queen Anne Avenue N and Fifth Avenue N.
  • Queen Anne Avenue N will have one northbound lane and two southbound lanes between Roy and Mercer Streets.
  • Left turns from westbound Mercer Street onto southbound Fifth Avenue N will be available.
  • Left turns from eastbound Mercer Street onto northbound Dexter Avenue N will not be allowed for approximately one year.
  • Access to northbound SR 99 from eastbound Mercer Street will be via southbound Dexter Avenue N onto westbound Thomas Street.
