PHILADELPHIA -

Officials say they will move forward with a $6.4 billion plan to expand Philadelphia International Airport without displacing neighboring residents.

Regional leaders have announced a resolution to a years-long dispute that had kept the project in limbo.

The agreement includes annual payments to Tinicum Township, and eliminates a proposal to acquire 72 adjacent homes and relocate about 300 residents. It still requires federal approval.

The expansion is designed to make the one of nation's busiest airports more competitive by reducing delays and adding capacity and services.

Plans include a new runway, an automated people mover and a new ground transportation center within the next 15 years.

The airport served more than 30 million passengers last year and accommodated more than 400,000 takeoffs and landings.
