The NJDOT is planning on widening the route in Hillsborough to four lanes and adding a concrete median from Doctor's Way to Brown Avenue, where the four lane highway south of the Raritan River ends. This will replace the railroad bypass that is primarily blocking the widening project. The first half, from Doctor's Way to Valley Road, will start in the summer of 2020 and is anticipated to be completed by fall 2022. The second half, from Valley Road to Brown Avenue will take place in 2022 and take 2 years to complete.
