The West Swanzey Covered Bridge (also known as the Thompson Bridge) is a historic wooden covered bridge carrying Main Street over the Ashuelot River in West Swanzey, New Hampshire.

Milky Way & night sky
From West Swanzey Covered Bridge, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.0 hours on a moonless night), and the core peaks around 18° above the southern horizon. Our light-pollution model puts the sky at about Bortle 5 (suburban sky), so expect visible sky glow; drive away from towns for better results.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 5 Bortle 5 — Suburban sky. The Milky Way is weak near the horizon and washed out overhead; long exposures pick up a sky glow. Modeled zenith brightness ≈ 20.08 mag/arcsec². Aurora needs roughly Kp 5.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 51% average cloud cover) and December as the cloudiest (68%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this covered bridge
- Many covered bridges still carry traffic; stay off the roadway and watch for vehicles.
- 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.
- Check road and trail conditions with the managing agency before you go.
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.
