20th Street Bridge and Roadway Improvements

The City and County of Denver is performing bridge and roadway rehabilitation work on the elevated portion of 20th Street over the South Platte River between I-25 and Little Raven Street.

This critical improvement project incorporates bridge repairs such as a new concrete overlay, expanded joint replacements, deck repairs and a new painted railing and is funded by the city's capital improvement program.

The project is scheduled to be complete in winter 2022/23.
