Lafayette fire officials closed a two-block portion of Pinhook Road for about 2½ hours Wednesday afternoon when a company doing construction work ruptured a 4-inch gas line along the roadway.

Officials evacuated two businesses near the corner of Pinhook Road and Commission Boulevard, where the leak originated, Lafayette Fire Department spokesman Alton Trahan said.

About another 120 nearby residents were without gas and electrical service for a few hours while CenterPoint Energy — which owns the line but was not responsible for the rupture — worked to restore the pipeline, Trahan said.

Gas emitted from the pipeline for about an hour-and-a-half before CenterPoint clamped the leak, which was first reported at 1 p.m., Trahan said. Although the roadway reopened at 5 p.m., officials were still working on Wednesday evening to permanently repair the line.
