The foundation works for the roundabout are also 100 per cent complete, with curbing at 50 per cent. Additionally, work on the Burnham Drive approach is advancing, with subsurface works at 38 per cent, curbing at 39 per cent, and culvert works currently underway.

Meanwhile, the Eastern End of the bridge is 27 per cent complete, accounting for foundation and retaining structures. At the time of the visit, 3,750 prefabricated vertical drains had been installed and geotextiles laid, with the contractor currently placing white sand and crushed stone as part of the subsurface works.

A new culvert at the Washer Pond Road approach at Noitgedacht has been successfully installed, and construction is underway for the retaining wall of the main embankment. Excavation and geotextile installation are complete, with backfilling ongoing to prepare for final surfacing.

The project remains on track to be fully operational by June 2026, pending the completion of the connector roads. When finished, the toll-free crossing will feature two barrier-separated pedestrian walkways, modern lighting, and two new roundabouts on both the eastern and western sides of the bridge.

The Ministry of Public Works remains committed to delivering high-quality infrastructure that meets the growing demands of Region Ten and the wider country.
