After a five-week closure, Oshawa Executive Airport reopened Monday evening.

The rapidly expanding facility’s main 4,000-foot runway was rebuilt from two metres below ground to end a persistent maintenance headache caused by frost heaves. A new gravel base was installed, emergency overruns added and a berm to ease noise for an adjacent neighbourhood installed. Total cost of the project was $5.5 million.

There’s also a new Nav Canada tower.
