The Colorado Department of Transportation has begun use of 18 new Variable Speed Limit (VSL) signs along Interstate 70 west of Vail, in Dowd Canyon, between Mile Points 169 and 173. The VSL signs were brought online in mid-January, replacing the area’s older static speed limit signs. The newly installed signs are LED electronic versions of traditional speed limit signs. Eighteen variable speed limit signs throughout Dowd Canyon have been brought online and former static speed limit signs have been removed as of Jan. 12, 2026. The speed limit posted on the VSL signs is the enforceable speed limit, not a suggested speed.
