Improvements To Start Mid-September On Canyon Ferry Road

Helena, Montana (date)  The Montana Department of Transportation
(MDT) and Helena Sand and Gravel will begin construction September
13, 2021, on the Canyon Ferry Road and Lake Helena Drive tied

The Canyon Ferry Road project starts at RP 0.0 and extends
approximately 5 miles east, just past the intersection of Danny K
Lane and Canyon Ferry Road. The Lake Helena Drive project begins at
the intersection of Old Highway 12 at RP 0.0 and extends north ending
south of the intersection with Lewis Street.

Construction includes
minor bridge upgrades, crack seal, plant mix pavement, and seal and
cover (chip seal). Additionally, the project includes upgraded
pavement markings, signage, and guardrail. The purpose of the project
is to improve the road surface, upgrade safety features, and increase
the longevity of the roadway.

From mid-September through the end of
October, the traveling public should expect reduced speeds, single
lane traffic controlled with flaggers and/or traffic signals and
delays up to 15 minutes. Portions of Lake Helena Drive may be closed
during paving operations. Seal and cover operations will occur during
summer 2022. 

For the safety of the public and construction workers,
MDT encourages motorists to plan ahead, allow extra travel time, slow
down, and use caution through work zones. Motorists should consider
seeking an alternate route during peak commuting hours. Current
construction information and road conditions throughout Montana can
also be found on the MDT Travel Info App at
