The state altered 13 with a new four-lane route along DeYoung Street in the late 1950s.

A half-mile later, the busy four-lane route passes the south side of the State University of New York at Albany's highly modernistic campus.

But NY 16 runs parallel to the freeway and remains a four-lane route, although no longer divided, following the Olean valley.

Business US 27 is a variable two and four-lane arterial route running north to south of the downtown, concluding at US 27 at both terminus's.

At the junction with International Boulevard, it expands to a four-lane divided route from there to I-84.

NY 303 begins as a four-lane route with mostly full access, and it retains this status until Valley Cottage.

This four-lane route is less than 0.75 mile (1.21 km) in length.

The four-lane divided route will have as many as two lanes closed at a time, transportation officials say.

Construction began on the new four-lane route at this location in 2008.

East of exit 147, Interstate 20 once again becomes a four-lane route until mile marker 155.
