Saudi Arabia's Roads General Authority (RGA) says it has carried out more than 6,500 linear meters of expansion joint work on bridges as part of its 2026 road maintenance programme. Actual progress stands at 86.2% across 22 projects in several regions.

By type, asphalt joints are 99.5% done and mechanical joints designed for 100 to 200 millimeters of movement are finished. Mechanical joints with a 50 to 100 millimeter range are at 87.2%, while those rated for less than 50 millimeters have passed 20%, with 938 meters still being installed. The authority expects to complete all targeted work by the end of the year.

Expansion joints let road and bridge structures absorb the expansion and contraction caused by heat and limit water leaking into structural elements. Their upkeep involves site inspections, cleaning, repairs to fixings and seals, and tracking any defects that could affect performance or the life of the asset.

The RGA monitors bridge needs through its Bridge Management System, a digital platform that records, inspects and evaluates bridges over their whole life cycle, forecasts future defects and repairs, and estimates the costs and budgets needed for maintenance planning.

Bridges are inspected regularly because constant exposure to harsh weather and shifting traffic loads makes them more prone to wear and corrosion than other structures. Spotting and fixing problems early, the authority said, improves safety, reduces risks to traffic and makes maintenance more cost-effective.
