Traffic detours expected during TVC roundabout construction Published April 22, 2009 By 21st Space Wing Public Affairs PETERSON AFB, Colo. -- To improve base traffic flow, Tierra Vista Communities began construction on a new roundabout at the intersection of Stewart Avenue and Malmstrom Avenue, April 22. Phase one of the project is expected to last one month and involves creating a detour, which includes closing Malmstrom Avenue south of Stewart Avenue to Glasgow Avenue in both directions. To access Malmstrom Avenue south of this area, traffic will detour to Suffolk Street and be rerouted east on Ent Avenue. This detour is scheduled to be in place for approximately three months. Construction personnel will direct and stop traffic at various times during construction hours. During all phases of construction, Tierra Vista Communities will communicate road closures and traffic interruptions through the Space Observer and TVC website, www.tierra-vista.com. Detour maps will also be displayed at various locations on base including the base exchange, the commissary, fitness center, pharmacy and the wing command building.
