The new state Route 167 Puyallup River Bridge opened ahead of schedule Sunday.
Crews had the bridge ready at 10 a.m., 19 hours earlier than expected, the state Department of Transportation said.
The project replaced the steel-truss bridge built in 1925.
To connect the new bridge, workers had to close all lanes of traffic over the weekend.
The new span has wider sidewalks, and the northbound overwidth and overheight restrictions were removed.
