Plan for significant southbound I-5 delays near Vader for Cowlitz River Bridge work Sept. 12-16

One lane closed around the clock, except weekends and Labor Day week

VADER – People living and driving near Toledo and Vader in Lewis County will need to plan for extended delays on southbound Interstate 5 starting Sept. 12.

Southbound I-5 near the Cowlitz River Bridge will be reduced from two lanes to one and the State Route 506 on-ramp to southbound I-5 will be closed around the clock during the following times:

  • 8 p.m. Monday, Sept. 12, through 10 a.m. Friday, Sept. 16

During the closures, Washington State Department of Transportation contractor crews from Granite Construction will remove non-cement bridge deck patches and replace them with concrete patches.

Travelers may encounter significant delays of more than 30 minutes in the morning and up to an hour during peak afternoon travel times. People should consider rescheduling discretionary trips, delaying travel if possible or using an alternate route. Before heading out, sign up to receive email/text construction updates, view the WSDOT real-time travel map or upload the free WSDOT mobile app.

Ahead of the lane closures, travelers will follow advanced directional signs guiding them to begin shifting from two lanes of traffic down to a single lane. For everyone’s safety, the speed limit will be reduced from 70 mph to 55 mph through the work zone.

Northbound I-5 lane closure

Once complete with the southbound lanes, crews will do similar preservation work on northbound side. One of two lanes of northbound I-5 near the Cowlitz River Bridge will be closed Sept. 19-23 and Sept. 26-30.

Work on the I-5 Cowlitz River bridges is part of the regionwide bridge deck patching pilot project to extend the useful life and smooth the decks of several bridges throughout southwest Washington. This $3.8 million project is scheduled for completion this fall.

Slow down on ice and snow.

It's easier to skid or lose control traveling at higher speeds. Give yourself more time to stop.

Carry chains, practice installing them.

Winter conditions could mean chains are required on your route. Practice putting them on your vehicle ahead of time.

Pack your winter car kit.

Carry extra supplies like warm clothing, ice scraper and brush, jumper cables and other emergency items.
