Current Activity

Posted Tuesday, Oct. 2

This project is almost complete. The contractor finished constructing the core of the dam, which is made of clay. Work to the shell of the dam, which is made of sand, is almost complete. Next steps include adding riprap or rock on the slope of the dam, installing drainage pipes at both ends of the dam, and rebuilding the road that is on top of the dam. Partial dredging of the two reservoirs of the lake will take place at the end of September (weather permitting). Project construction is scheduled to be finished this fall.

Albemarle Avenue will remain closed until construction is complete - Vehicle and foot traffic is not permitted in areas directly surrounding the bridge. Please use designated detours. Work hours will be Monday through Friday from 7 a.m. to 6 p.m. with no work scheduled on the weekend except in an emergency or with prior approval from the City.

If you have any questions about upcoming construction, contact Gilles Bellot, PE, at Gilles.Bellot@raleighnc.gov or 919-996-4001.

History

The City of Raleigh approved the rehabilitation of Lower Longview Lake as a Capital Improvement Program (CIP) project in 2008. In 2009, Albemarle Avenue was closed at the dam due to deterioration of the bridge superstructure, which has caused the bridge to be unsafe for vehicle traffic. Instead of approaching the project with a temporary repair to the bridge, City staff has established a more sustainable and long-lasting design. Albemarle Avenue will remain closed until the dam rehabilitation project is complete.
