DETROIT (AP) - The closings of three air traffic control towers in the state of Michigan are among 149 nationwide that will be delayed.
The Federal Aviation Administration said Friday it needs more time to deal with legal challenges to the closures announced because of government-wide spending cuts.
The planned tower shutdowns include those at W.K. Kellogg Airport in Battle Creek, Coleman A. Young in Detroit and Sawyer International in Marquette County's Sands Township.
Sawyer is the largest airport in the Upper Peninsula.
The FAA said all of the airport towers, which are operated by private contractors for the agency, will be closed or turned over to local authorities on June 15.
The closings were expected to begin Sunday.
The new schedule implements the shutdowns at once, rather than gradually.
Battle Creek officials had entered into a contract to keep the tower open.
