Don't Panic

What's Happening?

A section of Alexander Street, between Lawrence Drive and Canal Pointe Boulevard, will close for about six months beginning on Wednesday, November 6, 2019, as the New Jersey Department of Transportation and Mercer County replace aging bridges and a culvert that span the Delaware and Raritan Canal, Stony Brook and Alexander Creek.

Why?

The bridges, which are over 70 years old, are in poor condition and too narrow for today’s traffic. Their replacements will be safer, wider, improve traffic flow and include shoulders and sidewalks on both sides.

What's the Detour Route?

The official detour route will follow Faculty Road to Washington Road to Route 1:

You will be able to travel along Alexander Street up to the Metro North restaurant. It and all businesses along Alexander will remain accessible (you can continue to patronize our local businesses along Alexander). Residents of Lawrence Apartments and patrons of the Springdale Golf Club will access those locations via Lawrence Drive from Alexander Street.

Who's Involved?

NJDOT and Mercer County are working cooperatively to simultaneously replace bridges under each of their jurisdictions. While the University isn’t responsible for construction, we are working with state, county and local officials, as well as members of the community, to help minimize traffic-related impacts. We are grateful to NJDOT and Mercer County for coordinating their work.

What Are the Impacts?

Construction won't prohibit traveling to campus, but it will make it more time consuming. Commute time into and out of Princeton and travel time between campus and offices along Route 1 will increase, sometimes significantly. Expect the biggest delays during the morning and evening rush (7:00 a.m. to 10:00 a.m., and 3:00 p.m. to 7:00 p.m.).

Route 1 and its crossings into and out of Princeton will see the greatest impact. Other roads, such as Mercer Street/Princeton Pike, Route 206 and Route 27 will see more traffic congestion than usual. Local streets in town may take longer to drive, especially during the evening rush. Heavy rain risks closing Quaker Road, which will add traffic to other routes.

What You Can Do

The best way to beat the traffic is good planning. Princeton University has created this website to help you stay informed, know your options and make plans that are right for you.

How Project Delays Can Happen

Weather -- rain, snow and cold can impact the project's completion. Unforeseen construction issues can arise, and can lead to delays beyond the planned April 20, 2020 completion date.
