As part of its 4-year $85 million statewide initiative to bring ramps and sidewalks into Americans with Disabilities (ADA) compliance, a contractor for the Colorado Department of Transportation will begin work next week to upgrade 71 local curb ramps at 29 locations. Weather permitting, the project begins Monday at 7 a.m. on State Hwy. 392/Main St. and 7th, 8th and 9th Streets.Here are a few details about the project, although CDOT expects minimal traffic impacts:• Once complete, curb ramps along both State Hwy. 257 & 392/Main St. will be ADA compliant.• Working hours are Mon. to Fri., 7 a.m. to 4 p.m., holidays excluded.• Work will be performed with minimal impact to motorized and non-motorized traffic. • Anticipated completion is expected in late September.Upgraded ramps will be wider, sloped for easier access by the public, and finished with a slip-resistant texture for additional safety in all weather conditions. The materials used in their construction will be fast drying, ensuring full pedestrian and vehicle access within 24-hours of each ramp’s completion. CDOT is minimizing travel impacts to vehicles and pedestrians for the duration of this project by employing the following measures: single lane closures may exist Monday to Friday between 8 a.m. and 2:30 p.m.; shoulder and sidewalk closures will be in place during ramp demolition and replacement; signs and flaggers will be in place to safely direct traffic; and access to residential driveways and businesses will be maintained during construction.For more information, including lane closures and other traffic notices, visit http://www.COTrip.org .
