Design-Built Structural Solution

The Frances Appleton Bridge was part of the master plan to restore the iconic 1908 Longfellow Bridge across the Charles River between Boston and Cambridge. The older, obsolete pedestrian bridge next to the historic bridge was replaced with this wider, ADA compliant structure that better complements the arches of Longfellow.

The new bridge deck arch is contemporary in appearance and very transparent, in order to not obstruct views of Longfellow Bridge, the river, and parkland.

The slender main steel arch span is on the order of 222 feet (68 m) long and are connected to approach ramps that appear to float over the landscape before settling next to the river.
