Underground Utility Work to Limit Access on Center Drive Near Clinical Research Center

The Office of Research Facilities is installing underground duct banks for electrical feeders to the Clinical Research Center (CRC). This extensive work, will be conducted in multiple phases, with the first phases closing portions of Center Drive, beginning on August 17.

During the first phase (Zone 1), a western portion of the CRC Access Road (inner loop) will be closed in both directions and traffic re-routed via the outer loop. During the second phase (Zone 2), a western portion of Center Drive (outer loop) will be closed in both directions between the CRC and the Northwest Child Care Center. The CRC Access Road (inner loop) will be used as the detour route. Access to the child care center will remain open.

  • Phase 1 (Zone 1): Monday, August 17 – Monday, August 24*
  • - CRC Access Road (Center Drive Inner Loop).

  • Phase 2 (Zone 2): Tuesday, August 25 – Thursday, September 3*
  • - Center Drive Outer Loop

* In the event of inclement weather, start and end dates are subject to change.

During both phases of construction, cones, barrels and fencing will encompass the construction site. Detour signs will direct traffic and temporary sidewalks will be constructed around the work zone. While Center Drive is under construction, motorists are encouraged to consider using alternative routes to cross campus.

Project C104552: Replace Steam Lines Between Manhole 69 and Manhole 101, Convent Drive

Starting later this month (August, 2020) the Office of Research Facilities (ORF) Division of Technical Resources (DTR) will be replacing 450 ft of steam lines that are part of a major campus distribution system along Convent Drive. This project will involve excavation along Convent Drive and will cross Lincoln Drive, tying in at each end to existing steam manholes. The present steam lines have developed several leaks over the past eight years and are at the end of their useful life. These steam lines (which were installed in the early 1960’s) form part of a critical redundant system for the southwest part of the campus and are in need of replacement.

During construction, there will be intermittent lane and sidewalk closures. Signs will be posted for pedestrian detours and any lane closures will be staffed with flagmen when needed. The access to MLP 8 for vehicular traffic along Lincoln Drive will not be affected.

The construction duration will be from September 2020 through December 2021. For safety reasons, vehicles and pedestrians are encouraged to be aware of the changing surroundings as the project progresses through the coming year. Periodic updates will be provided through the ORF Intranet website.
