More nighttime closures are planned on Interstate 5 in Federal Way this weekend, according to the state Department of Transportation.
On Friday night, crews will close all I-5 southbound lanes and two northbound lanes at state Route 18. They will reopen by 7 a.m. Saturday.
Also closing Friday night are the westbound SR 18 off-ramp to southbound I-5 and the southbound I-5 off-ramp to eastbound SR 18.
On Saturday night, all northbound lanes of I-5 at SR 18 will close until 7 a.m. Sunday. The eastbound SR 18 off-ramp to northbound I-5 and northbound I-5 ramp to westbound SR 18 will also close Saturday night.
The work is part of a $112 million project to build two flyover ramps that are expected to open by the end of this year.
