US 287 CO 1 to LaPorte Bypass

(as of March 21, 2018)

Construction continues on the US 287 project between CO 1 (Terry Lake Road) and LaPorte Bypass. To date, crews have installed 68,000 square yards of concrete, 6,400 linear feet of concrete pipe ranging in size from 18- to 54-inches, 45,000 pounds of reinforcing steel, 56,000 cubic yards of embankment material, and 35,000 tons of aggregate base material.

Installation of phase 2 storm sewer pipe is nearly complete on the south side of US 287 by Meadow Lane.  Work on storm sewer inlets will continue between Aragon and the roundabout. Road base installation and concrete pavement installation will follow over the next several months. Access for residents and businesses continues to be maintained at all times throughout the work zone.

Work on the roundabout located west of North Shields Street is expected to resume beginning in April or as soon as weather allows for adequate thaw of base material and when temperatures are warm enough for concrete to be poured.

The estimated completion of the project is late fall 2018.

Traffic Impacts

  • Expect one lane open in each direction on US 287 between CO 1 and the LaPorte Bypass, as well as continuing shoulder closures throughout the project.
  • Speed limits are reduced to 30 mph throughout the construction zone. Fines will be doubled for speed violations.
  • Expect occasional lane shifts and temporary lane closures to allow for trucks and equipment entering the highway.
  • Construction hours are 7 a.m. - 7 p.m., Monday through Friday.

Project Overview

On Feb. 15, 2016, CDOT started construction on US 287 north of Fort Collins. Construction is expected to be completed by the fall of 2018.

CDOT will construct and widen US 287 just north of Fort Collins city limits beginning at Colorado Highway 1 (Terry Lake Road) to the intersection of CR 54G (LaPorte Bypass). The existing two-lane asphalt road will be replaced with four through-lanes, center turning lane, 10-foot shoulder/bike lane of concrete pavement and 7-foot-wide concrete sidewalks. The LaPorte Bypass signalized intersection will be replaced with a 228-foot roundabout.

This $21 million project will improve traffic flow as well as provide safe walkways for pedestrians. The project will provide increased safety for the traveling public as well as an aesthetically pleasing entrance to the North College corridor.


This is a Responsible Acceleration of Maintenance and Partnerships (RAMP)-funded project that allows CDOT to fund multi-year projects based on year of expenditure, rather than saving for the full amount of a project before construction begins.
