Why are manhole covers round? A manhole cover is round because it won’t fall through the opening on which it sits, it can simply be rolled to reach a destination much faster, while applying relatively little effort. Courtesywww.scienceabc.comCOUNTY News:
Beginning Monday, July 1, crews will be adjusting manholes in the Ponderosa Estates area.
This work will begin on Aspen Drive at Range Road and continue along Aspen Drive, Sumac Lane and Maple Drive before finishing back at Aspen Drive.
Since there a dozens of manhole adjustments in this sub-division, construction is scheduled to go through July 31.
The concrete being used is a high strength mix and will require a cure time, residents are urged to avoid driving over these manholes for the first few days after they are poured.
Traffic control will be set up daily in several locations along the project route and residents are urged to use caution when driving through and walking near these work zones. The work is scheduled to begin at 8 am and end by 5 p.m. each day.
