Overview Fig. A


Maine’s transportation network connects us to each other and to the world. Together, roads, rails, airports, and seaports can support an integrated transportation system that promotes economic activity by getting goods and people to their destinations efficiently and affordably. Public transportation is a critical component of this system, allowing people to access employment and services without a car, and reducing congestion and pollution.

Our roadways carry the vast majority of passengers and freight. Poor road conditions can lead to personal injury, property damage, and extended commute times. The Maine Department of Transportation grades roadways from A (excellent) to F (unacceptable). This measure shows grades for the most-traveled and economically significant (“Priority 1”) roadways.

In 2022, 989 miles (67%) of Priority 1 highways were graded A, B or C, up 1% from 2021. Four hundred ninety-two miles (33%) were graded D or F.
