Sections of vehicle lanes on Grand Avenue and North Perimeter Road will be closed and re-routed from 10 a.m. Wednesday through 5 p.m. on Thursday.
The closing may cause delays for motorists, but California Boulevard and Highland Drive can be used as alternative routes if necessary.
The closure is for field crews to access the manholes and underground utility areas, and partial lane restrictions are necessary for both worker and motorist safety.
“The work is to inspect underground utilities as part of the Student Housing South project,” said Jessica Hunter, customer services specialist for Cal Poly. “Accessing the manholes, and full or partial road closures take place as needed for a variety of reasons such as maintenance, repairs or in this case to support new construction.”
Drivers using Grand Avenue and North Perimeter Road are urged to observe cone lines, detour signs and traffic direction.
Though the road was not under construction as of Wednesday morning, Hunter said workers could be out at any time on Wednesday or Thursday.
“The notification is intended to cover a range of time where work may occur,” she said. “Notifications regularly will cover a more broad range of time than we ultimately use. It’s better for us to “over-notify” than “under-notify.”
