The I-405 freeway in Portland will close this weekend for installation of the new Flanders Crossing bridge.
At 10 p.m. Friday, I-405 will close in both directions between the Fremont Bridge and Highway 26.
It'll reopen Monday morning at 5 o'clock.
The Flanders Crossing is a new pedestrian and bike bridge that connects the Pearl to Northwest Portland.
During the closure:
• Signed detours will direct drivers to Interstate 5.
• All northbound traffic on I-405 must take Exit 1D, 12th Avenue/U.S. 26.
• All southbound I-405 traffic, including traffic from the Fremont Bridge, must take Exit 2A/2B, Everett/Couch/Burnside.
Crews will set up traffic control and begin mobilizing for bridge installation on Friday, Jan. 22 at 10 a.m. On Saturday, Jan. 23, Flanders Crossing will be installed using two cranes and two 12-wheel trailers on either end of the bridge to move the 355,000-pound truss bridge into place over Interstate 405. The installation is expected to begin at around 9:30 a.m. and will last approximately 8 hours until the bridge is in its final place. On Sunday, crews will disassemble the bridge launch equipment and sweep and inspect I-405 before reopening the interstate to traffic. Installation of the bridge is contingent on wind speeds. Wind gusts of 35 mph or higher will prevent the bridge from being installed.
