The ongoing fire activity is affecting one of the state’s primary east-west freight routes while also creating challenges on nearby highways that commercial traffic often depends on when detours become necessary.

Interstate 84 Has Reopened, but Conditions Remain Unstable

Interstate 84 reopened early on July 29 after fire activity forced an overnight closure. Firefighters continue to work near a 30-mile section of the interstate between Baker City and Ontario, where changing conditions could require intermittent closures if fire behavior worsens.

Wildfires are also affecting portions of U.S. 20 and U.S. 26 in eastern and central Oregon. Even highways that remain open can be affected quickly as fires shift direction, smoke reduces visibility, or emergency crews need additional access to the roadway.

ODOT advises travelers to expect conditions to change throughout the day rather than assuming a route will remain open from departure to arrival.

Detours Can Create New Challenges for Commercial Traffic

Closing a major interstate does not simply move traffic onto another highway. According to ODOT, many secondary roads were never designed to accommodate sustained volumes of heavy commercial vehicles, and congestion develops quickly once traffic begins diverting away from a primary freight corridor.

Long backups, slower travel speeds, and a greater risk of crashes become more common under those conditions, particularly where two-lane highways carry a mix of passenger vehicles, emergency equipment, and commercial trucks.

GPS navigation can also become problematic during wildfire events. ODOT warns that some navigation systems may direct drivers onto Forest Service roads or other routes that are unsuitable for large commercial vehicles. Checking official roadway information before leaving a primary highway can help prevent unnecessary detours.

Waiting Near a Closure Can Leave Drivers With Few Options

Truck parking areas, fuel stations and other services located near highway closures often reach capacity as commercial vehicles wait for roads to reopen. Once those locations fill, drivers may have limited access to fuel, food or overnight accommodations while closure times remain uncertain.

Rather than driving toward an active closure, ODOT recommends remaining in an area where essential services are available until updated road conditions indicate travel can resume safely.

Smoke Is Only One Part of the Hazard

Dense smoke can reduce visibility quickly, but it is only one reason highways are being restricted. Firefighters and emergency responders are working alongside many affected roadways, while some highways are also serving as evacuation routes for nearby communities.

Wildfires can create additional hazards even after flames move away from the highway. Damaged guardrails, missing traffic signs, and debris may remain until repair crews can safely enter the area. Power outages caused by fires may also disable traffic signals, requiring drivers to treat dark intersections as four-way stops under Oregon traffic laws.

Because wildfire conditions continue to evolve across eastern Oregon, ODOT advises checking TripCheck.com throughout the trip instead of only before departure. A route that appears open in the morning may change significantly by the time a driver reaches the affected area.

The widening effort, which started in 2024, is expanding I-5 to three lanes in each direction through the Salem area. Traffic has already shifted in several locations, and posted speeds have been reduced through the work zone.

Overnight lane reductions are underway on January 9

Work on the Battle Creek Road Bridge is now impacting traffic near mile marker 250. Overnight hours are most affected.

Through the early morning of Friday, January 9, I-5 is reduced to one lane in each direction between 9 p.m. and 5 a.m. Drivers traveling overnight should expect slowdowns and congestion, particularly for heavy trucks moving through the corridor.

Full nighttime closures are scheduled for next week

Additional impacts are scheduled to begin next week with full overnight closures between Exits 248 and 252.

Those closures are planned for January 12 through January 14, running nightly from 10 p.m. to 5 a.m. Detours will be in place during the shutdowns.

Northbound detour

• Exit at 248
• Commercial Street SE
• Right on Kuebler Boulevard
• Re-enter northbound I-5

Southbound detour

• Exit at 252
• Kuebler Boulevard
• Left on Commercial Street SE
• Re-enter southbound I-5

All work remains weather-dependent and subject to construction needs, the Oregon Department of Transportation said.

Additional traffic pattern changes drivers should expect

Beyond the scheduled closures, ODOT has outlined several long-term changes that will affect how trucks move through the area.

Southbound I-5 traffic will be shifted onto what were previously the northbound lanes. Northbound drivers will use Exit 249 and the former on-ramp as the new northbound lanes.

Access from south Commercial Street to southbound I-5 will be limited to a single lane connection. A concrete barrier will separate northbound traffic from vehicles coming off Delaney Road, and traffic from Delaney Road will no longer be able to access the Commercial Street ramp.

Wiltsey Street SE remains closed at the Battle Creek Road SE intersection and is expected to stay that way until mid-2026. Drivers can detour using 36th Avenue SE north to Kuebler Boulevard.

What the project is addressing

According to ODOT, the first phase of the widening project focuses on the long-standing southbound bottleneck and congestion along the hill south of Salem.

Work in this phase includes replacing the bridge over the Commercial Street northbound off-ramp and the Battle Creek Road Bridge. The project also includes a new roundabout, paving improvements, and sound walls.

The work stems from an environmental study of the I-5 corridor between the Hayesville Interchanges and Battle Creek Road that was completed in the mid-1980s and approved by the Federal Highway Administration and the state in 1988.

What drivers should do now?

Drivers running overnight through the Salem area should allow extra time, confirm detour routes in advance, and avoid tight appointment windows during closure hours when possible. With lane shifts and access changes continuing, even daytime runs may see unfamiliar traffic patterns.

More project details and updates are available through the official project website, and drivers are encouraged to check conditions before rolling through the area.

According to ODOT, the superloads contain no hazardous materials, fuels, or liquids. The shipments will travel at speeds of 10 to 30 miles per hour along designated routes, including U.S. 730, OR 37, Interstate 84 in Pendleton, U.S. 395, U.S. 26, and OR 201, before exiting Oregon into Idaho via OR 201 near Adrian. Oversized loads will operate from the Port of Morrow through Pilot Rock during nighttime hours and from Pilot Rock to the Idaho border during both daytime and nighttime hours. When not in transit, the loads will park off the main roadway.

Due to the extreme size of each shipment, both travel lanes on two-lane highways will be used, causing traffic delays. Vehicles will experience periodic stops, and pilot cars will escort the shipments, guiding them along the route. Designated pull-over sites will allow superloads to stop and give waiting vehicles a chance to pass.

ODOT urges all drivers to stay vigilant when encountering pilot vehicles escorting these oversized or overweight loads, as safety remains a top priority. Special permits and traffic management plans have been established to reduce risk for all road users along the transport routes.

What is a Superload?

A superload is a unique classification of oversized loads in Oregon. The term applies to shipments exceeding the following dimensions:

• Width: Over 16 feet on Interstates or over 14 feet on two-lane state highways (excluding certain mobile units with widths including up to a 12-inch eave).
• Height: Over 17 feet on any highway.
• Length: Greater than 150 feet overall.
• Mobile Units: Those with a width exceeding 14 feet for the box or a total width greater than 15 feet.

Motorists are encouraged to plan for these transports and allow extra travel time when driving along affected routes.
