At 0922 central time, a McDonnell Douglas MD-88 operated by Delta Air Lines collided with parked construction trucks at Houston Hobby Airport. There were no injuries. The flight had been cleared to cross runway 22 and taxi to the gate. The pilot taxied on taxiway Zulu, which is parallel to taxiway Yankee, which was open. Taxiway Zulu was closed due to construction; however, the construction was not posted on the ATIS, NOTAM, or dispatchers release from the company. Ground control did not mention that taxiway Zulu was closed.
