July 28, 2017: South Broadway Reconstruction Project Wraps Up

Denver Public Works has reconstructed a stretch of South Broadway from Kentucky to Arizona and a section of Mississippi Avenue between the Consolidated Main Line (CML) Railway and Sherman Street. The project began in March 2016 with the goal of improving overall mobility for people on bikes, on foot and in vehicles. 

 

DESIGN
Broadway/I-25 Wedge Ramp


The current phase of the redesign and improvements to the Broadway/I-25 intersection will focus on the southbound on-ramps (from Broadway to southbound I-25) and the reconstruction of Broadway from Ohio Avenue to Exposition Avenue.

 

The City and County of Denver's Broadway Arizona to Exposition Project will be constructed in three to four phases. As each phase is funded for construction, the City and County of Denver (City) will follow the Federal Highway Administration (FHWA) guidelines for acquisition of required properties within the project corridor. This guidance provides the City will follow their standard process of completing Right-of-Way plans, then City Council passing an ordinance authorizing property negotiations and acquisitions. Upon ordinance passage the City will contact affected property owners and begin the negotiation discussions, offers will be made after appraisals or value finds are completed. The City reserves the right to utilize imminent domain, but will continue to negotiate to meet fair value agreements through the acquisition process.

Planning/Engineering

Final Design Project Scope

The overall project scope for these two projects will reconstruct South Broadway from Kentucky Avenue to Arizona Avenue and Mississippi Avenue between the Consolidated Main Line Railway (CML) and Lincoln Street. Improvements will include roadway widening; multi-use paths from Arizona to Kentucky along Broadway and from the CML to Sherman along Mississippi; pedestrian and street lighting; landscape and streetscape; and upgraded signalized intersections at Broadway/Tennessee and Broadway/Mississippi.
