The Rachel Carson Bridge, also known as the Ninth Street Bridge, in Downtown Pittsburgh.

One of Pittsburgh’s three “Sisters Bridges” connecting Downtown to the North Side will close in February for more than a year during a $23.3 million rehabilitation project, Allegheny County announced Monday.

The Ninth Street Bridge, dubbed the Rachel Carson Bridge, will close on February 11 and remain closed through the summer of 2020, according to the county. Allegheny County owns the structure.

The Rachel Carson Bridge opened in 1926.

Traffic will be detoured via the neighboring Seventh Street Bridge, also known as the Andy Warhol Bridge, to Isabella Street in the North Side and back onto Ninth Street.

Workers for Brayman Construction and Advantage Steel and Construction, both headquartered in Saxonburg, will replace the bridge decking, sidewalks, drainage systems and lighting and make repairs to structural steel. They will repaint the bridge in its landmark Aztec Gold color.

The finished bridge will have new traffic patterns with three lanes of travel and wider shoulders. The bridge now has four lanes.

The Sister Bridges include the Warhol, Carson and Roberto Clemente bridges. Each crosses the Allegheny River between Downtown and the North Side.

Allegheny County finished a similar rehabilitation project on the Andy Warhol Bridge in 2017 and plans to upgrade the Roberto Clemente Bridge between 2021 and 2022.
