SR 504 is the state highway from Castle Rock. The forest roads reach recreation areas on the south and east sides, and their seasonal status can differ from the state highway.
SR 504, the Spirit Lake Memorial Highway, runs east from Castle Rock on I-5. As checked September 28, 2026, WSDOT closes it at the winter gate at milepost 45.2. A May 2023 slide destroyed the Spirit Lake Outlet Bridge farther east. WSDOT expects bridge work to finish in spring 2027, followed by Forest Service work at Johnston Ridge Observatory. See the project update.
On the south side, Forest Roads 90 and 83 lead toward Ape Cave and Lava Canyon. Ape Cave is on the 8303 spur. Road 83 above Marble Mountain Sno-Park has a winter gate. Check the Forest Service conditions page for road and recreation-site closures.
Forest Road 99 reaches Windy Ridge from Road 25 on the east side. Road 99 closes for winter. Check both roads before choosing an approach.
The September 28, 2026 feed check returned the WSDOT camera on SR 504 at milepost 33. The map also loads agency reports and NIFC fires within 25 miles. An empty alert list does not establish that a road is open.

A different question from whether SR 504 is open. The visibility page reads the cloud ceilings between Portland and the summit and answers it for Portland, Vancouver, Woodland and the I-5 towns.
The cameras, closures and road reports come from WSDOT. Wildfires come from the national NIFC feed. Tap any camera on the map, or in the list, to see its latest frame.
Whether SR 504 is open and whether you can see Mount St. Helens are different questions. The visibility page reads the cloud ceilings between you and the summit and answers the second one for Portland, Vancouver, Woodland and the I-5 towns.
