Princeton University has developed a special website that will provide project updates and other relevant information to the Alexander Street bridge closure. New Jersey Department of Transportation and Mercer County transportation officials expect the most congestion at the start of the project as commuters find new ways to work.

Please see below for possible transportation options during this time.



No changes to parking assignments or parking rules as a result of the closure.


Four routes will be impacted by the bridge closure:

  • 100 Overlook/701 Carnegie Center shuttle will provide service between Princeton Junction, 100 Overlook, 701 Carnegie Center, and 693 Alexander from 7:30 am to 5:30 pm, Monday – Friday. The route has been scheduled to meet Junction-bound Dinky trains in the AM, and campus-bound Dinky trains in the PM. (no IDs needed)
  • 693 Alexander shuttle will provide service between main campus and 693 Alexander, 100 Overlook, and 701 Carnegie Center. This route will not service Princeton Junction. Traffic on Route 1 will directly impact on-time performance of this route, particularly during peak commuting hours.
  • PTS West shuttle will operate as an express route with only two stops—401 Emmons Drive at the CRW Apartments off Canal Pointe Road, and at the crosswalk between the Princeton Theological Seminary and PTS Library on Mercer Street. (See here for alternative transit options for other PTS West stops).
  • Saturday and Sunday Shopper shuttles will service Lawrence and Lakeside routes in reverse order from the standard route—the shuttle will stop at Lawrence first when outbound from Graduate College, and will stop at Lakeside first when inbound from the shopping center.

New schedules will be reflected in Transloc beginning November 6. Remember to use TransLoc to check the status of the next bus and anticipate delays on all routes, particularly during the early days of the project.

Dinky Rail Pass Subsidy:

All benefits-eligible employees can apply to receive a 50% subsidy on monthly Dinky rail passes during the bridge closure to bypass local traffic whenever possible. Participants in the Dinky Rail Pass Subsidy program can retain their University parking permits or existing Revise Your Ride membership during the road closure.


SKIP TRAFFIC by taking public transit and save $$ with University benefits.

  • Considered making transit your primary commute? Save 50% on transit to campus with Revise Your Ride, PLUS additional pre-tax savings with HR’s Commuter Benefits program.
  • Not looking to take transit every day? Pre-load a set amount pre-tax and use to purchase individual transit tickets with the Commuter Pre-Tax Benefits Commuter MasterCard and use your University parking permit on your non-transit days. If you don't use all your pre-tax transit dollars, the amount will roll over to next month.
  • Don’t live within walking distance of a station? Drive and park at your local transit station and pay transit parking expenses pre-tax.  


The less cars on the road, the better the traffic situation will be for everyone. Princeton hosts an exclusive carpool database called Zimride. Log in with your University credentials and search for and message potential carpool partners. Don’t see a good fit? Post your ride for others to find and be automatically entered into Zimride’s Zimsgiving sweepstakes (Nov 1 – 30).

SHIFT YOUR COMMUTE to avoid peak times

Expect the biggest delays between 7-10AM and 3-7PM. See for details on the University's policies for flexible and remote work arrangements.

MERGE strategies to increase your flexibility

No one can predict exactly how the next couple of months will go, but we do know that the road closure will change all of our existing commute habits. Consider combining strategies to give you more options:

  • Find a carpool partner to the train station to share parking costs.
  • If you are considering different hours, use Zimride to look for potential carpool partners to split driving responsibilities.
  • Transition between options as available and appropriate, including public transit, carpool, remote or flex work, bike, walking, etc.
