Drivers traveling through the Ferndale area should plan for a five-hour road closure Wednesday, September 9, as BNSF Railway makes repairs at the railroad crossing where Loomis Trail Road meets Portal Way. The crossing will be fully closed from 10 a.m. to 3 p.m., and Whatcom County Public Works has established marked detour routes for vehicles that would normally use that intersection.
The closure affects the crossing itself, not the full length of Loomis Trail Road or Portal Way. Motorists approaching from either direction will be directed around the work zone via signed detour routes. County officials are asking drivers to follow posted signage and allow extra travel time, particularly during the midday hours when work is expected to be underway.
Where This Closure Fits in the Area
The intersection of Loomis Trail Road and Portal Way sits in the agricultural and industrial corridor north of Ferndale, a stretch that sees regular truck traffic headed to and from farms, warehouses, and commercial operations in the county's northwest lowlands. This part of Whatcom County is characterized by flat delta farmland, berry fields, and a network of county roads that carry heavy freight loads during harvest seasons in late summer and fall. The BNSF main line through this corridor carries both freight and some passenger trains, and periodic track and crossing maintenance work is routine throughout the year.
Portal Way is a key north-south connector road running from Ferndale toward Birch Bay and Blaine, serving as one of the primary routes linking the I-5 corridor to the communities along the western edge of Whatcom County. Loomis Trail Road functions as an east-west connector, linking the Portal Way corridor to areas further east toward Lynden and the agricultural heartland of the Nooksack Valley. Drivers who use the crossing regularly to move between those corridors, including farm equipment operators, freight trucks, and commuters, will need to find alternate paths during the five-hour closure window.
The BNSF main line at this location is part of the Spokane Subdivision, one of the busiest freight rail corridors in the Pacific Northwest. It carries coal, grain, intermodal freight, and Amtrak Cascades passenger service. Keeping crossings in good working order is both a federal safety requirement and a practical necessity given the train volume on this line. Surface repairs at rail-highway grade crossings typically involve removing and replacing the rubber or concrete panels that vehicles drive over, resetting the rail hardware, and inspecting the warning signal systems on both sides of the tracks.
Whatcom County Public Works manages the road network around the crossing and is coordinating the closure with BNSF. The railroad is responsible for the track and crossing infrastructure itself. This kind of joint closure is common when rail companies need to perform work that requires removing the crossing surface or making repairs that would be hazardous with live vehicle traffic overhead. The five-hour window is long enough to complete most crossing surface replacements while still allowing the road to reopen before the evening commute.
What to Expect and When It Ends
The work window runs from 10 a.m. to 3 p.m., a span deliberately chosen to fall outside of the heaviest morning and evening commute periods. Midday closures of this type are standard practice for BNSF and county road teams because they minimize disruption to commuters while still providing enough daylight hours to complete the work safely. If repairs proceed on schedule, the road should reopen by mid-afternoon. County road alerts note that travel delays should be expected, so anyone with a firm appointment or delivery window during those hours should budget extra time or identify an alternate route before leaving home or the worksite.
Drivers accustomed to using the Loomis Trail Road and Portal Way crossing have several options depending on direction of travel. Those needing to move between Portal Way and points east can consider Badger Road or other parallel county roads that cross the BNSF tracks at different grade crossings. The signed detour routes established by Whatcom County Public Works are the most straightforward option, as they will account for any restrictions on alternate crossings as well.
For the most current road status, Whatcom County's newsflash page posts road closure and restriction updates as they are issued by the Public Works department. Drivers can also check the county's extended road restrictions list, which is updated regularly and includes closures of longer duration across the county road network. That list is particularly useful in the fall months when utility work, culvert replacements, and other annual infrastructure maintenance projects layer additional temporary closures onto the system.
This closure comes just days before the BNSF Railway and local roads face additional scrutiny from the start of the Whatcom Chief ferry dry dock outage, which begins September 12 and runs through early October. That dry dock period affects Lummi Island Ferry service and can shift traffic patterns on roads leading to the Gooseberry Point terminal, including portions of Portal Way and connecting routes in the Ferndale area. When ferry riders are rerouted or experience longer waits due to reduced vessel capacity, some of that traffic redistribution lands on the county road network. Travelers moving through the Ferndale-to-Blaine corridor over the next several weeks should monitor county road alerts for any additional closures or detour adjustments as multiple infrastructure projects run concurrently this fall.
Knowing about closures in advance makes a genuine difference for residents and businesses in this part of the county. Farmers moving equipment between fields, feed supply companies making deliveries, and contractors working harvest-season jobs all depend on predictable access to roads in the Portal Way corridor. The county's practice of posting advance notice on its newsflash page gives those users time to adjust schedules rather than encounter an unexpected blockage mid-route.
