 The road heads in a more south-southeast direction the next 10 miles (16 km).The NY 311 exit offers the last connection to NY 52, a short distance to the south over Lake Carmel, and after crossing Metro-North's Harlem Line the interchange with NY 312 offers access to the large strip mall on a hill southeast of the exit and the Southeast train station.After a quarter-mile long (400 m) bridge over the Croton River, US 6, US 202 and NY 22 just north of Brewster, the Interstate returns to its eastern heading for the northern terminus of I-684, an exit that also provides access to the other three highways.
