Detroit Metropolitan Airport is getting a new radar system designed to ease congestion and reduce the risk of runway collisions.

The airport is the 13th nationally to install and operate the technology. The 14.5 million-dollar system is expected to be unveiled in late June.

The Federal Aviation Administration says Metro Airport is the nation's 11th-busiest based on take-offs and landings.

The FAA also awarded the airport a 5.1 million-dollar grant to help pay for energy and climate-control units at its under-construction North Terminal.

The system already is used at the airport's McNamara Terminal.
