Would you accept a six-week road closure for a long-lasting infrastructure fix?
Pittsburgh's Department of Mobility and Infrastructure will close Carnahan Road in Banksville between Younger Avenue and Banksville Avenue for approximately six weeks beginning in November 2026, while a 100-foot retaining wall is built to stabilize the hillside. Local traffic is permitted from Younger Avenue to Crane Avenue, and a detour runs via Crane Avenue and Banksville Road.
Why it matters
The closure affects drivers and commuters on a corridor that feeds Banksville Road, a major South Hills route, and serves Banksville Elementary School. The wall is intended to secure long-term roadway access, so the work reflects a stabilization project rather than routine resurfacing.
The project closes roughly one half-mile of Carnahan Road for approximately six weeks while a 100-foot retaining wall is built. The extraction does not provide cost, contract value, or traffic-volume figures for comparison.
The players
Pittsburgh Department of Mobility and Infrastructure
The city agency that manages street closures, roadway maintenance, and infrastructure projects within Pittsburgh's public right-of-way.
A. Merante Contracting
A West Mifflin-based contractor that performs site work and retaining wall construction for public infrastructure projects.
The details
Crews will build a retaining wall along the hillside next to Carnahan Road to stabilize the slope. While the wall is under construction, drivers will be routed onto a detour via Crane Avenue and Banksville Road in either direction, and Younger Avenue to Crane Avenue will remain open to local traffic only. West Mifflin-based A. Merante Contracting is the contractor performing the work.
Timeline
November 2026: closure of Carnahan Road between Younger and Banksville Avenues is scheduled to begin.
Approximately six weeks after the start of the closure: Carnahan Road is expected to reopen.
Market Landscape
Pittsburgh's hillside neighborhoods rely on retaining walls to keep steep roadways safe and open, and projects like this one follow that pattern. The work sits within the city's broader role as the public owner of these corridors, which determines how contractors such as A. Merante are engaged.
Fleet operators and commuters who use Banksville Road should plan for a detour via Crane Avenue during the closure window. Businesses in Banksville that depend on delivery routes should factor in longer transit times for the roughly six weeks of work.
The takeaway
Operators who route vehicles through Banksville should build the Crane Avenue detour into schedules for the six-week period. Monitor the city's announcements for the exact start date, since the extraction gives only a November 2026 window.
What happens next
Carnahan Road closure is scheduled to begin in November 2026 and last about six weeks, with reopening expected at the end of that period.
