Freshly paved roads feel great under any set of wheels: automobile, motorcycle, bus, bicycle, scooter, or skateboard. Unfortunately, our roads steadily deteriorate with time, use, and New England weather. Investments are made in roadway maintenance to extend pavement life and keep rides smooth. Pavement condition is measured using the present serviceability index (PSI), a measure of a road’s roughness that accounts for patch work, rutting, and cracking. PSI scores range from zero (impassable) to five (perfectly smooth). Engineers consider a score of two or three as the minimum acceptable PSI.
Scroll down to compare pavement conditions on non-interstate roadways in the region’s cities and towns. The first column presents the overall distribution of pavement segments on the National Highway System and all MassDOT-owned non-National Highway System roads by their PSI score, with the average value highlighted. The second and third columns display the percent of pavement and the total lane miles of pavement on these roadways with acceptable PSI scores, respectively.
Select a city or town from the list to see how the pavement conditions on non-interstate roadways on the National Highway System and all MassDOT-owned non-National Highway System roads within the municipality have changed over time. Each line charts the PSI value of a segment of a non-interstate road over the past decade.
