The Hillsborough River Bridge is a bridge crossing the Hillsborough River estuary between Charlottetown and Stratford in Queens County, Prince Edward Island. The current road bridge, built in 1962, replaced a 1905 rail bridge crossing the same span which was known by the same name. As the Trans-Canada Highway project was planned in the 1950s, improving the crossing of the Hillsborough River was deemed essential. A new, improved 2-lane road bridge was built immediately upstream of the old rail bridge, opening in 1962. The bridge was widened to carry 4 lanes of traffic in 1995.
