General News

The Week & Weekend Ahead: February 18, 2020
  • Ames Construction will be installing two conduits across E. Colfax Avenue, which will require temporary, full lane closures across Colfax around Jackson Street. To minimize disruption to residents, businesses and commuters, current plans are to perform the work between 10 p.m. Saturday, February 22 and 5 a.m. Sunday, February 23.
  • Crews conducted work on water lines beginning at 10:30 p.m. on Saturday, February 8. Work was completed earlier than anticipated, with water fully restored to residents and businesses by 5 a.m. on Sunday, February 9. Thank you for your patience and understanding while crews performed this critical work.
  • The westbound lanes of E. Colfax around Jackson Street will remain closed during the first phase of construction. The eastbound lanes of E. Colfax will remain open (with the exception of the conduit installation on February 22-23, mentioned above) and adjusted during this time to provide one eastbound and one westbound lane for traffic.
  • Please note that vehicles traveling westbound on Colfax Avenue are able to turn right on northbound Harrison Street for access to local businesses and the neighborhood. Businesses in the project area are open during construction.
  • During the first phase of construction, the sidewalk on the north side of E. Colfax around the intersection at Jackson Street will be closed.
  • The lane closures on E. Colfax necessitated temporarily moving the entrance to National Jewish Health (NJH) to 14th Avenue. Signage has been added to help patients find that entrance. Additionally, pedestrian access to NJH is currently located on 14th Avenue.
*Construction is also underway on the National Jewish Health new Center for Outpatient Health on the northwestern most section of the former patient parking lot, situated at E. Colfax Avenue, between Jackson and Garfield Streets. For more information about this project, please visit https://nationaljewish.org/center-for-outpatient-health/overview.

Project Background

In early January, Denver Department of Transportation & Infrastructure began pre-construction work for the installation of an improved, expanded storm drain system to provide greater flood protection for Congress Park residents, National Jewish Health (NJH) patients and staff, and local businesses from heavy rainstorms and other storm events. In addition, the new Jackson Street Storm Drain infrastructure will ultimately provide additional capacity for the upstream area around Hale Parkway.
The Jackson Street Storm Drain Project will begin on the north side of E. Colfax Avenue at Jackson Street. Work will proceed south across E. Colfax, through the existing City right-of-way (ROW) in the National Jewish Health (NJH) parking lot and continue on E. 14th Avenue at Jackson Street for ½ block east towards Harrison Street. The entire project will take approximately 18 months.

General Construction Impacts

Residents and Businesses: Access to residences and businesses will be maintained during construction.
Pedestrian Traffic: Sidewalks on the north side of E. Colfax at Jackson Street will be closed during installation of the new storm pipe in that intersection for the first phase. Please be aware that this project involves digging deep ditches to make way for the new storm pipe. For safety reasons, pedestrians are asked to avoid fenced off areas and to cross only at traffic signals.RTD: The RTD stop at E. Colfax and Colorado Boulevard will remain open during construction. While crews work in the westbound lanes of E. Colfax, the bus stop at Garfield Street may be impacted. Additionally, it is possible that the bus stop next to NJH will be temporarily closed when work shifts to the eastbound lanes of E. Colfax. Updates will be provided as the project progresses.
