(Astoria, Oregon) - The Oregon Department of Transportation (ODOT) has been busy along the coastline – and that will continue during this summer's busy season. Some amount of travel interruptions will happen in the Astoria area, near Garibaldi and in the north and central Coast Range. (Above: in the Miami Foley Road area / Oregon Coast Beach Connection)

At the very tip of the Oregon coast, the Astoria-Megler Bridge will see daytime closures over the summer. From mid-June through September, expect single lane daytime closures periodically.

“If you haven't heard already, we're replacing some of the bridge supports and concrete bases,” ODOT said. “While most of the work will happen below the bridge, we'll need daily single lane closures for the safety of our crew and the traveling public.”

Look for Daytime single lane closures with flaggers and temporary traffic signals helping direct traffic.

The Astoria-Megler Bridge is the longest continuous truss bridge in the U.S. Its truss is 1,232 feet long, which surpasses all other continuous trusses in the country and makes it one of the longest of its kind in the world.

Also in the Astoria area, preparations are underway for repairs on the Skipanon River Bridge. Crews have begun clearing vegetation and setting up the work zone. The project requires closing Fort Stevens Highway Spur Road on both sides of the bridge for approximately 60 days. The full road closure on OR 104S is scheduled to begin on June 16 and last around two months. A signed detour will direct traffic via OR 104, E Harbor Drive, Marlin Avenue, and U.S. 101. Pedestrian access across the bridge will not be available during the construction period, and delays are expected. Astoria Maps and Virtual Tours

ODOT is working on Miami Foley Road (near Garibaldi and Wheeler) to replace the temporary Crystal Creek bridge and the Dry Creek culvert with two new permanent bridges.

It had announced a full closure on May 30 but that has been moved to June 5.

Typically, a full road closure is required when constructing new bridges, ODOT said, but this project is being approached differently. Instead of shutting down the road entirely, each bridge is being built one lane at a time to reduce traffic disruptions. As a result, vehicles will be able to pass through the work zone on a single lane for most of the construction period.

Traffic has already been detoured once, and following the June 5 closure, drivers should anticipate two additional detours while equipment is transported to the Crystal Creek site via U.S. 101.

During the June 5 closure, Miami Foley Road will be shut down on both sides of Dry Creek from 7 a.m. to 5 p.m., requiring a detour via U.S. 101. Crews will be working throughout the day, and motorists should expect construction noise and delays. By 5 p.m. on June 5, one lane of Miami Foley Road is expected to reopen with a temporary traffic signal managing the flow of vehicles. Construction work will continue during the daytime hours, and minor delays are expected.

Further daytime closures are anticipated at Crystal Creek, although ODOT has not yet provided specific dates. Updates will be shared once the schedule is confirmed.

Both the Dry Creek and Crystal Creek culverts were in deteriorating condition and required replacement. In 2023, a severe storm washed out the Crystal Creek culvert, prompting an emergency full road closure for repairs. Now, ODOT is constructing two permanent bridges to replace the temporary structures.

Meanwhile, ODOT has completed work on the new bridge at Little Humbug Creek. The U.S. 26 bridge over Humbug Creek was rebuilt in two phases last year, with half of the bridge constructed at a time. Final work was completed this year, including the application of permanent striping. ODOT thanked the public for its patience, noting that closing one lane at a time allowed the project to be completed faster while minimizing costs and limiting environmental impacts in the Siuslaw National Rainforest.

Elsewhere on the Oregon coast, construction crews will begin installing rumble strips on highways across Northwest Oregon. Work is set to start on OR 18 and OR 22 next week, followed by OR 99E, U.S. 26, and U.S. 30. Some work zones may be active on multiple highways simultaneously. Drivers should anticipate lane and shoulder closures, with crews working mostly during the day and occasional night work. Motorists are urged to exercise caution and watch for workers in construction zones.

Rumble strips, which are grooves in the pavement that create vibration and sound, are designed to alert drivers when they begin to drift out of their lane. Studies have shown that these safety measures can reduce roadway departure fatalities by up to 64% and are a cost-effective way to improve road safety.
