East County Line Road - Zlaten Drive to St. Vrain Creek

Project Background

The Public Works Department, in partnership with the City of Longmont, is planning to widen East County Line Road from Zlaten Drive/Great Western Drive to St. Vrain Creek (see a map of the project area).

The widening will:

  • Add seven-foot wide paved shoulders to a short section of East County Line Road to provide continuous paved shoulders from Longmont down to Quicksilver Road and the city’s St. Vrain Trailhead.
  • Improve road geometry to eliminate an offset lane alignment on southbound East County Line Road.
  • View project exhibits

Schedule and Travel Impacts

Construction is anticipated to last through February 2025, weather permitting. Expect single-lane closures during daytime, weekday working hours, 8 a.m. to 4:30 p.m.
