The left, northbound lane will be closed on the blue bridge from about 9 a.m. to noon Wednesday.
Washington state Department of Transportation crews will be replacing a steel cover on the concrete barrier that divides the northbound and southbound lanes on the bridge, said Darin Wilkens, bridge supervisor for DOT's south central region.
A department snowplow hooked the steel cover and popped it off in December, he said.
