A major east-west corridor in south Sacramento County has reopened to traffic after Union Pacific Railroad completed a five-day track maintenance project that forced thousands of commuters onto lengthy detour routes. Twin Cities Road was closed from a half mile west of Highway 99 to Christensen Road, affecting a key connection between several south county communities.
According to Fox40, Union Pacific adjusted track elevations to fix uneven pavement at the crossing, then repaved the roadway to provide travelers with a smoother crossing over the train tracks. The Sacramento County Department of Transportation coordinated the shutdown, which began July 28 and extended through the work week.
During the closure, SacDOT provided detailed detour instructions for affected drivers. As reported by Fox40, eastbound travelers could navigate around the work zone by heading south on Christensen Road, then east on Spring Street, and north on West Stockton Boulevard to reconnect with Twin Cities Road. Residents living near the repair work maintained access to their homes throughout the closure period.
Part of Broader Infrastructure Maintenance
The Twin Cities Road project reflects ongoing railroad crossing improvements across the Sacramento region. Just days after this closure ended, South Watt Avenue between Florin Road and Elder Creek Road was scheduled for weekend work to allow California Central Traction Company to upgrade railroad crossings, according to Sacramento County officials.
The South Watt Avenue Improvement Project aims to enhance railroad crossings while adding traffic lanes, sidewalks, and bike lanes. These concurrent projects highlight the extensive coordination required between transportation agencies and railroad companies to maintain aging infrastructure where roads and railways intersect.
Growing Infrastructure Demands
Railroad crossing maintenance has become increasingly critical across Sacramento County as aging infrastructure meets growing traffic demands. The county placed message boards along affected routes to guide drivers through the temporary changes, though many commuters experienced significant delays during peak traffic hours when alternate routes became congested.
Major rail improvement projects continue across the broader Sacramento region, with Valley Rail train service anticipated by 2026 and construction scheduled for various grade separation projects in 2025. The successful completion of the Twin Cities Road work demonstrates the effectiveness of coordinated planning between SacDOT and railroad operators, though similar closures are likely as infrastructure throughout the region requires ongoing maintenance and upgrades.
