When completed in 1908, it was significant for its early use of concrete in bridge construction and as the world's largest concrete arch bridge. Reformers of the era praised its utility and design. Connecting Germantown and Roxborough, it reduced the travel time between the two neighborhoods from a half-day to minutes, and promoted business and social interaction. This engineering marvel remains a vital transportation artery for Philadelphia.
