The City of Arvada and contractor partner, Jalisco International, are beginning a year-long project to widen the intersection of Indiana Street (Colorado Highway 72) and 72nd Avenue.

Please note: Speed limit reductions are anticipated and fines are double within the work zone. The project is weather-dependent and the schedule is subject to change. Updates to the road closure schedule will be posted here as information becomes available, so check back often.

What to Expect

Indiana Street and 72nd Avenue--Currently

  • Intermittent lane closures with alternating traffic from 8:30 a.m. to 3:30 p.m., Monday through Friday.
  • One lane in each direction will be provided whenever possible during working hours and when work is not taking place.
  • Occasional night and weekend work is expected.
  • The west leg of West 69th Avenue at Indiana Street will be temporarily closed for similar work later this summer. This work has been rescheduled due to utility conflicts. 

Project completion is expected in summer 2019.

Project Overview

Plans to improve the intersection have been in development since 2013. This $7-million project is funded through the City’s Capital Improvement Project Fund. Planned intersection enhancements will improve the safety and functionality of the intersection. This project will raise the profile of the roadway to improve drainage, upgrade the traffic signal and provide additional capacity through the intersection. The  new intersection layout has been designed to accommodate future traffic volumes. Two lanes in each direction will be provided through the intersection and Indiana Street will be widened to accommodate double left-turn lanes in both directions. Other project improvements include:

  • New sidewalks and on-street bike lanes
  • Undergrounding utilities
  • Water line replacement
  • Storm sewer upgrades
  • Bridge expansion on 72nd Avenue over Croke Canal
