South Frontage Road West lane closure in Intermountain through June

Flaggers, temporary traffic light, will manage single-lane alternating traffic in the open lane.


A portion of South Frontage Road West between Stephens Park and Elliot Road in Intermountain will operate with alternating one-way traffic through June due to an infrastructure improvement project undertaken by the Eagle River Water & Sanitation District and town of Vail.

The temporary traffic lights on South Frontage Road West will operate outside of work hours to allow travelers safe passage through the work area.

The district is installing new sewer main that will increase sewer main capacity in the West Vail area so it can accommodate peak sewer flows in the future. The district is partnering with town of Vail to install electrical conduits to allow for the removal of the existing overhead power lines. The district and town are cooperating to complete both improvements while reducing impacts to the public.

The work requires one lane of the road in the project area to be closed at all times. Motorists and non-motorists can travel in the remaining lane via alternating one-way traffic 24-hours a day. Flaggers will manage traffic operations during work hours – generally 7 a.m. to 7 p.m. – and automated traffic lights will manage traffic at night. The public should plan for delays of up to five minutes in the work area.

While it may be slightly inconvenient, public safety during construction is paramount, and additional roadway width is not available due to deep excavation and conflicts with other existing utilities. Anyone who uses that stretch of road – from skateboarders to bicyclists to motorized vehicles – must comply with flaggers and traffic lights at all times for their safety due to narrow conditions on the one lane that is open. The traffic lights are located on the east and west ends of the project area and are set to allow sufficient time for travelers to clear the affected area before allowing travel in the opposite direction.

The Intermountain work is Phase 1 of a two-phase project this summer, which is the second project in a district-wide capital plan to address growth and meet water quality regulations for at least the next 20 years. Phase 2 of the project is located east of the Exit 173 roundabout, near the West Vail Conoco; it will start in mid-July and take approximately two months. Significant traffic impacts will exist in this area and motorists are advised to use alternate routes where possible (North Frontage Road and the new Sandstone underpass, for example) as one lane will also be closed in this area.
