Route 133 (also known as the Hightstown Bypass) is a 4.06-mile-long (6.53 km) freeway located entirely in East Windsor, Mercer County, New Jersey in the United States. The route runs as a four-lane bypass of Hightstown from Princeton–Hightstown Road (County Route 571 [CR 571]) and 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 [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 I-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 $57 million Route 133 commenced on September 20, 1996, and was completed and opened on November 30, 1999.
