Resurfacing work on Princeton-Hightstown Road from and Clarksville Road to Slayback Drive began on April 25 and is expected to take about two weeks.
The milling and paving repairs are being handled by Mercer County under the American Recovery and Reinvestment Act project. All work on Princeton-Hightstown Road will be done in the evening due to the heavy daytime traffic volume.
Work will then progress to Clarksville Road, from North Post Road to the easterly Everett Drive intersection, officials said.
Work is being performed by Arawak Paving Group.
