Overview
Route 133 (also known as the Hightstown Bypass) is a short state freeway located entirely in East Windsor Township, Mercer County, New Jersey in the United States. The route runs as a four-lane bypass of Hightstown from County Route 571 (CR 571) at Windsor Center Drive to the New Jersey Turnpike / Interstate 95 (I-95) at exit 8. Originally, Route 133 did not have any direct connections to any other freeways until a new Turnpike interchange opened in January 2013.
The plans for the original bypass of Hightstown originated in 1929, when locals looked for a way to remove traffic from downtown. The New Jersey State Legislature followed up in 1938 by designating a new spur off of State Highway Route 31 (then part of U.S. Route 206 or US 206), State Highway Route 31A as a freeway from Princeton to the Jersey Shore. During the 1970s, the highway proposed as Route 92 gained momentum, running from Princeton (at Interstate 95's proposed Somerset Freeway) all the way to Route 33 at Hightstown. However, after several setbacks, Route 92 was moved northward in 1988 and the bypass was truncated to a short portion of highway bypassing Hightstown. Construction on the new US$57 million Route 133 commenced on September 20, 1996, by Schiavone Construction Company and was completed and opened on November 30, 1999.
Route description
Route 133 begins at an at-grade intersection with CR 571 (Princeton–Hightstown Road) in East Windsor. The intersection includes a jughandle for eastbound traffic to use to access the highway. After the jughandle allowing westbound CR 571 traffic to access Windsor Center Drive which continues southwest from the freeway, Route 133 begins to progress its way northward as a four-lane freeway, crossing through surroundings of trees and open fields. Along a large bend, the highway turns eastward, paralleling to CR 571 to the south and CR 535 (Old Trenton Road) to the north. Passing to the southeast of a McGraw Hill Financial office building, Route 133 curves to the southeast through fields and crosses over the locally maintained One Mile Road heading eastbound and interchanges westbound. Heading eastbound, the on-ramp to Route 133 from One Mile Road merges in, and the highway continues, passing to the north of homes and commercial buildings through East Windsor.
