Detours on Mountain Highway for watermain construction (June 28 through August)
Starting June 28, 2017, and lasting through August, there will be watermain construction along the 3200-3300 block of Mountain Highway, from Frederick to 3275 Mountain Highway (north of Lynn Valley Rd).
During construction, one lane of traffic will remain open northbound. Southbound lanes will be closed, with a detour in place.
Thank you for your patience as we complete this important work.
