CARRABASSETT VALLEY, Maine (AP) — One of the most popular ski resorts in New England has announced a decade-long expansion plan.

Sugarloaf’s plan for expanding includes developing almost 450 acres on West Mountain, WMTW-TV reported. The development will bring new alpine trails, downhill mountain bike trails, a tubing park and a new high-speed chairlift.

The expansion of Sugarloaf also includes new residential real estate and the construction of a 4,600-square-foot spa.

Representatives with Sugarloaf said construction will begin next year, and all of the planned improvements will be finished by 2030.
