A gas leak at Baltimore-Washington International Airport tied up vehicle traffic yesterday afternoon and prompted the temporary evacuation of three piers, airport officials said.
Construction crews were working on part of the airport's $1.8 billion expansion about 11:30 a.m. when they ruptured a gas line on the lower level outside the main terminal, said Cheryl Stewart, a spokeswoman for BWI.
Baltimore Gas and Electric Co. workers who responded to the incident determined that the gas leak was minor, so passengers were allowed back onto the piers --B, C, and D -- about an hour later, Stewart said.
Vehicles were not allowed to use the upper and lower roadways of the airport until about 1:30 p.m., Stewart said.
"The primary impact of the incident was on the roadways," said Jonathan Dean, a spokesperman for the airport.
He said a handful of flights into and out of the airport were canceled because of the rupture.
