The shuttle buses and vans for travelers and workers at Baltimore Washington International Thurgood Marshall Airport are continuing to operate today under an emergency contract, as the Maryland Aviation Administration works out kinks in the award of a new three-year, $45 million contract to First Transit Inc. of Cincinnati.

The previous contract expired Wednesday and State Transportation Secretary John Porcari asked the Board of Public Works to hold off awarding the new pact. Porcari told the board the contract had been held up because the award was being protested by a competing bidder.
