High Street (Portland, Maine)

High Street is a downtown street in Portland, Maine, United States. It runs one-way for around 0.81 mi, from Commercial Street in the southeast to Forest Avenue in the northwest. It is one of the three main routes crossing the Portland peninsula in this direction, the other two being State Street and Franklin Street. Part of the street passes through the Spring Street Historic District and the city's Arts District.

High Street and State Street were converted from two-way traffic in 1972.

Route
Running one-way for its entire length, High Street begins at Commercial Street, directly opposite Becky's Diner, on a steep incline. The slope is shared with Park Street, on the opposite side of the Irving gas station separating the two. The hill continues until it crests at Congress Street, which in this section is in Congress Square. From there, a steep decline begins to its intersection with Forest Avenue. The street passes through the eastern edge of Deering Oaks Park for its final 700 ft or so, before it intersects with Forest Avenue at the beginning of U.S. Route 302.

Streetcars of the Portland and Forest Avenue Railroad Company (chartered in 1860) formerly ran along High Street en route to Spring Street and Clark Street.
