The city will shut down a major intersection and Highway 99 interchange in north Modesto for slightly more than two days as part of an estimated $55 million construction project.
Modesto plans to close the Pelandale Avenue-Sisk Road intersection and the Pelandale-Highway 99 interchange for 50 hours, from 10 p.m. Sunday to midnight Wednesday so crews can work around the clock finishing highway offramps and reconstructing the intersection.
“We are going to work through the closures with alternating crews,” Modesto senior civil engineer Chuck Covolo said.
Modesto is replacing an interchange that was built in 1970, when the city’s population was about a third of what it is today. Construction started in May 2014 and is expected to wrap up by the end of this year. As part of the work, crews built a new bridge spanning the highway and demolished the old one over last summer.
Never miss a local story.
The area is a major retail hub, with the Wood Colony Plaza shopping center at the southeast corner of the intersection and the Northpointe Shopping Center – which includes the city’s Costco warehouse – at the northeast corner. The area draws tens of thousands of motorists each day.
Covolo said the city expects to open the new northbound and southbound offramps several hours after reopening the intersection early Wednesday. Signs and detours will be in place. The nearest highway interchanges are at Kiernan and Standiford avenues.
The city recently went to businesses near the intersection and interchange to inform them of the latest closure. The project has been a hardship for some businesses as some customers have avoided the area.
Covolo said the project remains on schedule and on budget.
