Bridge Slide Construction

Slide-in bridge construction is an accelerated bridge replacement method where a new bridge is built adjacent to the existing one and then slid into place, minimizing traffic disruption and construction time.OverviewSlide-in bridge construction (SIBC), also known as lateral or horizontal slide, is part of Accelerated Bridge Construction (ABC) technologies promoted by the Federal Highway Administration (FHWA) to reduce project delivery time, enhance safety, and limit traffic impacts during bridge replacement . This method allows the new bridge superstructure to be constructed on temporary supports beside the existing bridge, maintaining traffic flow until the replacement is ready .Construction ProcessPre-fabrication: Components such as deck panels, columns, and supports are fabricated off-site to ensure quality and speed .Temporary Supports: The new bridge is built on temporary supports adjacent to the existing bridge .Bridge Slide: After the existing bridge is demolished or moved, the new bridge is slid into its permanent location using hydraulic jacks, skid tracks, and push-pull units .Approach Tie-Ins: Roadway connections to the new bridge are completed, finalizing the replacement .Variations: In some cases, the existing bridge is temporarily slid to a bypass alignment while the new bridge is constructed in place .Equipment and SystemsSIBC relies on specialized skidding systems, including:Skid shoes and skid tracksHydraulic push-pull unitsMonitoring and control systemsTeflon pads or skid beams for smooth movement along straight or curved paths These systems allow bridges weighing up to 250 tons per shoe to be moved efficiently and safely .BenefitsReduced Construction Time: Replacement can occur in overnight to a few weeks, compared to months with traditional methods .Minimized Traffic Disruption: Traffic can continue on the existing bridge until the slide occurs .Enhanced Safety: Shorter work zones reduce risks for workers and travelers .Cost-Effectiveness: Pre-fabrication and rapid installation reduce labor and on-site costs .Environmental Advantages: Less prolonged construction reduces environmental impacts .Implementation and ResourcesThe FHWA provides implementation guides, cost estimation tools, and training workshops to help state DOTs, designers, and contractors adopt SIBC . These resources include case studies, planning guidelines, and step-by-step instructions for typical bridge replacements.Ideal ConditionsSIBC is most effective when:Adequate right-of-way (ROW) is available for temporary constructionTraffic maintenance is criticalRapid replacement is required due to safety or infrastructure needs ConclusionSlide-in bridge construction is a modern, efficient, and safe method for bridge replacement, combining off-site fabrication, temporary support construction, and lateral sliding to minimize disruption and accelerate project delivery. It is increasingly adopted in the U.S. as part of the FHWA's Every Day Counts initiative to modernize infrastructure efficiently .
