Tracy Road will remain closed between State Rt. 795 and Ayers Road as Columbia Gas crew make repairs to a natural gas line, authorities said.
The road closed Wednesday after an odor was detected coming from a manhole at the intersection.
Repairs may not be complete until Friday afternoon, said Chris Kozak, a Columbia Gas spokesman.
No disruption to gas service was anticipated, and residents were not in danger, Mr. Kozak said.
