Now that the pedestrian underpass project between the Aspen/Pitkin County Airport and Airport Business Center reached its halfway point, all traffic will be switched to the business center side of the highway. The traffic switch is slated to occur during nighttime hours on Sunday, September 15th. This will allow tunneling to begin from the business center toward the airport. All four lanes of traffic will be maintained as they have been during the project to date, although brief, intermittent lane closures should be expected. Motorists are advised to obey posted speed limits in the construction zone and use caution when driving through the area. Questions should be directed to Pitkin County Engineer, G.R. Fielding at 920-5206. From all of us at Pitkin County Government and RFTA, thank you for your patience during this project.
