Westgate Church is located at 100 Winter Street in Weston (see the red pin on the map below). Winter Street runs south from Route 30 (east of Route 27 and west of I-95/Hwy 128). The church is located just south of the Massachusetts Turnpike, but Winter Street cannot be directly accessed from the Turnpike.
From the north or east, take Route 128/95 to Route 30 west. Stay on Route 30 west, pass Weston High School on the left. Go through the next light, and take a left a few hundred yards ahead onto Winter Street. Stay on Winter St, go over the Mass Pike, and Westgate will be on the left.
From the west, take Route 30 east and go right on Winter Street (if you come to Weston High School, you have gone too far). Go south on Winter St., go over the Mass Pike, and Westgate will be on the left.
From the south, take Route 9 (Worcester Rd.) to Oak Street in Natick. Go north on Oak for 1 mile until you come to Winter Street. Go right on Winter Street for 2 miles, and the church will be on your right.
