The Office Bridge (also called Westfir Covered Bridge) is a covered bridge in Westfir, Lane County, Oregon, U.S. crossing the North Fork Middle Fork Willamette River at the south end of the Aufderheide National Scenic Byway and edge of the Willamette National Forest. It is Oregon's longest covered bridge at 180 ft (55 m), and is one of only two in the state using triple Howe truss construction. It is the only covered bridge west of the Mississippi River which has a separate pedestrian walkway. The bridge is a replacement for a 1941 bridge which washed away. It was built in 1944 by the Westfir Lumber Company to carry logging trucks and lumber trucks to the company's lumber mill and mill pond. The company headquarters and offices were located across the river beside National Forest Development Road 19, in what is now a bed and breakfast. The bed and breakfast retains the company's...From the Wikipedia article “Office Bridge”, licensed under CC BY-SA 4.0.

Estimated sky darkness: 4 Bortle 4 — Rural / suburban transition. Light domes are visible in several directions; the Milky Way is clear but lacks detail near the horizon. Modeled zenith brightness ≈ 20.74 mag/arcsec². Aurora needs roughly Kp 6.5+ to show low on the northern horizon here.

Weather & best season

Long-term NASA satellite data for this area show July as the clearest month (about 25% average cloud cover) and December as the cloudiest (75%). August is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this covered bridge

  • Overcast days keep contrast low between the dark interior and the bright surroundings.
  • Autumn foliage peaks are the most popular time — visit on weekdays to avoid crowds.
  • Shoot from the stream bank to show the bridge, the water and its reflection together.
  • Inside the bridge, the timber trusses make strong symmetrical compositions — use a tripod for long exposures.
  • Many covered bridges still carry traffic; stay off the roadway and watch for vehicles.
  • Bring a spare battery — cold weather and long exposures drain them fast.

Season: Peak fall color is the classic season; winter snow and spring blossoms are less crowded alternatives.

Suggested gear: Wide-angle lens, Tripod, Polarizer for foliage. Work out exposures with the depth of field, ND filter and NPF rule calculators.
