West campus projects

Campus road repaving and line painting

Roads across west campus (road west of and including Charter Street) will have asphalt repaired and line marking repainted throughout summer 2020. Traffic will be maintained on these roads, with workers with flags providing direction as needed.

Linden Drive parking structure and utilities projects

A section of Linden Drive between the Dairy Barn and Veterinary Medicine is closed May 26 until mid-to-late August.

Vehicles can enter and exit Lot 4, 123, 124, and 125 from Easterday Lane. A temporary driveway will also be available to Lot 123/the Veterinary Medicine loading dock from Farm Place. Lot 39 and 12 can be accessed from Linden Drive by way of Elm Drive.

Several area sidewalks and paths are unavailable while work takes place:

  • The southern sidewalk of Observatory Drive is partially closed; closed area extends from eastern edge of Lot 62 until the western edge of the new Meat Science building. Detour available via the northern sidewalk.
  • The northern and southern sidewalk of Linden Drive by the Linden Drive parking garage construction site is closed. Detour available via the Observatory Drive sidewalks.

Reminder: The Willow Creek pedestrian-bicycle bridge is closed until further notice due to structural integrity concerns.

Partial closure of Lot 131

A section of Lot 131 located near the intersection of Oxford Road and University Bay Drive will serve as a temporary landing pad for UW Hospital Med Flight during most of July. UW Med Flight will temporarily relocate starting July 6 as the UW Hospital landing pad undergoes repair work.  This switch is expected to last 2-3 weeks, depending on weather and other factors.

This off-street section of Lot 131 closed as of June 29 to undergo site preparation–likely closed until July 28.

This project was coordinated with guidance from UW Hospital, FP&M, Housing, and local government groups.
