Temporary Traffic Changes on Forbes Avenue

Starting Monday, March 25, traffic patterns near the Forbes Avenue and South Craig Street intersection will temporarily change to accommodate construction for the new Richard King Mellon Hall of Sciences. The following changes will remain in effect until project completion in fall 2027:

  • Vehicles turning left into the Carnegie Museums’ parking garage from westbound Forbes Ave. (leaving CMU’s main campus) will need to turn from the main traffic lane. The left turn lane will be closed.

  • Vehicles turning right onto eastbound Forbes Ave. when exiting the Carnegie Museums’ garage may need to turn from the main traffic lane. The right turn lane will experience periodic closures throughout the project.

  • All pedestrians crossing the Forbes Ave. bridge will need to use the sidewalk on the north side of the street (connecting TCS Hall and the Tepper Quad). The southern sidewalk will be closed between Craig Street and the Mehrabian Collaborative Innovation Center.

These changes will not impact CMU's current shuttle routes. Vehicle and bike lanes will remain open on Forbes in both directions throughout the project, as will the sidewalk on the north side of the Forbes Ave. bridge. Traffic-flow improvements will also be considered post-construction to help make this area safe and efficient for pedestrians, bicyclists, and bus and shuttle riders.

Traffic updates will be posted to CMU's Transportation Services website as they become available. To learn more about the Richard King Mellon Hall of Sciences, visit the university’s Campus Design and Facility Development website.
