ZELIENOPLE — Two of the borough’s Butler County-owned bridges are to be replaced next year.

Although the borough knew the Green Lane Bridge was definitely going to be replaced next year, borough manager Don Pepe said Monday night the borough got some good news that the county’s bridge crew also will replace the Market Street Bridge.

“We really need to thank the county commissioners because they really have done something good for us,” Pepe said.

The Green Lane Bridge was originally estimated to cost about $130,000, but is looking like it will cost about $90,000, Pepe said.

That project is expected to begin next spring just as school closes and be completed by the fall. It will be closed for three to four months.

The Market Street Bridge will be replaced during the same time period. The estimated cost for that project is $250,000.

Pepe said the county has asked the borough to help pay for new approaches to the bridge, which he recommended the borough do. The borough’s project cost would be about $30,000.

“It’s a different structure (the new Market Street Bridge). It’s going to be a larger bridge,” Pepe said.
