20th Street Improvements
20th Street Continues
In 2016, the Keep Greeley Moving Program expanded 20th Street, 74th to 83rd avenues, from a two-lane county road to a four-lane arterial roadway with medians and turn lanes.
This fall the City of Greeley will continue that project and widen 20th Street west of 83rd Avenue and add curbs, gutters, sidewalks, landscaping, and a drainage system — in addition to adding a roundabout at 20th Street and 83rd Avenue.
This continuation of the 20th Street project is not entirely funded by the Keep Greeley Moving program.
This project will widen 20th Street west of 83rd Avenue and add curbs, gutters, sidewalks, landscaping, and a drainage system — in addition to the new roundabout.
Expanding 20th Street helps ease traffic congestion near growing neighborhoods in west Greeley and increases safety for drivers and residents in the area.
Work keeps moving ahead on the 20th Street expansion. In mid-March, the closure will extend west to about 90th Avenue as expansion construction continues. That work should allow 20th Street to reopen near the end of June.
Just last week, crews finished the removal and disposal of contaminated soil uncovered during the construction. Near the start of February, construction crews doing ground stabilization work for a concrete drainage structure discovered a section of buried dirt several feet underground that looked abnormally dark and gave off a chemical smell. The dirt tested positive for oil-related chemicals.
Construction officials alerted the Colorado Department of Public Health and Environment (CDPHE) and brought in an environmental consulting firm to evaluate the situation, perform tests, and monitor the work. With the assistance of the environmental firm, crews removed and disposed the contaminated soil at a landfill that is designated by the EPA to receive such wastes.
Greeley stormwater staff have monitored the surface water in the area and found no additional contamination in the project site or additional damage to the environment. The testing and evaluation so far have not found a conclusive cause or source for the contaminated soil — however, officials will continue working with property owners in an effort to learn more about the source of the soil contamination.
The project widened 20th Street to four lanes and added left and right turn lanes from 74th to 83rd Avenue, street lighting, detached sidewalks, curb and gutter, storm sewers, bike lanes, and raised center medians along the corridor. Vehicle sight distance was also improved at the 82nd Street intersection.
Minor Arterials are streets that serve moderate-speed and higher-volume traffic over medium distances. Access should be restricted through prescribed distances between intersections and limited direct parcel access. Minor Arterials serve major traffic generators and link Collector streets with the Major Arterials.
The 20th Street Improvements Project widened 20th Street to four lanes and added left and right turn lanes from 74th Avenue to 83rd Avenue. The project also added lighting, detached sidewalks, curb and gutter, storm sewers, bike lanes, and raised center medians along the corridor. Vehicle sight distance was improved, which required extensive earthwork and relocation of underground utilities.
