Project Info

Project crews are removing and replacing five obsolete overhead and cantilever sign structures in the Denver Metro area. The old lattice-style structures were installed approximately 40 to 50 years ago.

The new structures will meet current design standards and wind load requirements. Sign structure removal under full highway closure is the last major work item for this project.
