Heads up motorists who travel on East Arapahoe Road east of Interstate 25 in Centennial. The City of Centennial is starting construction of a new dedicated underpass to improve trail connectivity and safety along the Lone Tree Creek Trail corridor at East Arapahoe Road between South Revere Parkway and South Potomac Street. The project includes the construction of a concrete box culvert under East Arapahoe Road. When completed next spring, it will allow trail users to travel beneath the roadway and eliminate crossing traffic at the South Revere Parkway crosswalk. To accommodate underpass construction, the project team has implemented a long-term traffic shift on East Arapahoe Road. Crews will begin excavation and fiber optic work in the coming week on the north side of the roadway. During the first construction phase this summer, crews will extend the existing culvert that carries Lone Tree Creek and start to build the new concrete box culvert under westbound East Arapahoe Road, along with associated walls. Motorists can expect the following travel impacts Monday through Friday on East Arapahoe Road: 9 a.m. to 3 p.m. Single eastbound lane closure from South Peoria Street to South Potomac Street. 10 a.m. to 3 p.m. Single westbound lane closure from South Potomac Street to South Peoria Street. The second and third phases of the project are scheduled to start later this year. Dates are weather dependent and subject to change. During the second phase, anticipated to start in the fall, traffic will be shifted to the outside of eastbound and westbound East Arapahoe Road. Work includes continued construction of the new culvert under the left turn lanes on westbound East Arapahoe Road. For the third phase, scheduled to start this winter, East Arapahoe Road traffic will be shifted to the north for construction on the south side of East Arapahoe Road. Crews will complete the new concrete box culvert and connect the underpass to sidewalks/trail connections and finish sidewalk work.
