CRANBERRY TWP — Motorists who use Main Street through Butler in the evenings and overnight this summer will face a detour for a major repaving project.

The state Department of Transportation on Thursday announced the work during an overview of projects the state will be performing this summer. The meeting was held at the Cranberry safety training facility.

The Main Street stretch of Route 8 in Butler will be paved starting May 1, from 6:30 p.m. to 6:30 a.m. daily.

PennDOT assistant district executive Paul Koza said the night schedule was chosen with traffic concerns in mind.

“We do try to look at the traffic volumes and try not to impact people too much,” he said.

The paving, to cost $820,900, will run from Wayne Street to Penn Street. The project end date was not reported.

Another project in the city is the replacement of the Cunningham Street Bridge.

That project, which will carry traffic over Sullivan Run, will cost slightly more than $2 million. The work will tentatively start May 8 and has a limit of 100 days to finish.

Another bridge project is already under way. Construction of the Zeigler Avenue Bridge began March 1. It will remain open for the duration of construction.

These bridge projects come a year after PennDOT replaced the West New Castle Street Bridge.

The Cox’s Corner intersection project in Clinton Township, Route 228 and Saxonburg Boulevard, was dubbed one of the bigger efforts of the year. The intersection, which is now a stop-sign controlled “T” intersection, will be converted into a roundabout beginning May 19.

It is a two-year project that will cost between $2.5 million and $5 million.

In all, the Butler County budget for the year is $24.6 million, including personnel, winter costs, equipment, paving, and system preservation.

“We should be able to (do everything in budget),” said PennDOT county facility maintenance services engineer Michael Shanshala.
