What to expect

Travelers should expect alternating one-way traffic with delays of up to 20 minutes. Traffic will be signal controlled for the duration of construction and flagger controlled depending upon construction needs. These controls may result in traffic delays of up to 20 minutes.

This project will include several nighttime full closures of the bridge with an established detour. The closures will take place between the hours of 10 p.m. and 7 a.m. and will be announced seven days in advance of each closure.

The SR 411 Cowlitz River Bridge in Cowlitz County will undergo a deck replacement beginning in the summer of 2022.
