North 83rd Street culvert replacement and resurfacing project starts June 21

Lane reductions and road closures planned to accommodate construction

Boulder County, Colo. - Boulder
County Transportation will begin a culvert replacement and roadway resurfacing
project on North 83
rd Street in Niwot starting at 8 a.m. on
Wednesday, June 21. The project boundaries are from Niwot Road on the southern
end to the Diagonal Highway/CO 119 on the northern end.

In
order to safely accommodate the project, the road will either be reduced to a
single lane in locations or completely closed. Work will take place between 8
a.m. and 4:30 p.m., Monday through Friday. Saturday work may be allowed, but
only if absolutely necessary to meet the project schedule. The project is expected
to last through October 2017.

A
portion of the Longmont-to-Boulder Trail and Niwot Loop Trail will be rerouted
during construction. Detour signage will be put in place. Access to the Left
Hand Grange Park and baseball diamond will be maintained via Niwot Road.

The
project includes:

  • A new reinforced,
    open-bottom, concrete box culvert at Dry Creek #2 that will accommodate higher creek
    flows
  • Resurfacing of
    one-mile of North 83rd Street
  • The
    road will be widened between Niwot and Neva roads to accommodate a new shoulder
  • New at-grade
    crossings for the Niwot Loop trail north of Niwot Road and the Longmont-to-Boulder
    Trail south of CO 119
  • New sanitary
    sewer main for Niwot Sanitation District
  • Reconstruction
    of the parking lot at Left Hand Valley Grange Park.
