Background information:

Construction of a new £5.9m railway bridge at the former Exxon site at Bowling is gathering pace. The new bridge will open up additional direct road access and enable the future development of the Bowling Strategic Development Site.

Work began in summer and has progressed on schedule. The bridge is now fully cast with around 1,860 tonnes of concrete, giving the bridge its shape.

The next major step will come over the Christmas and New Year period when the bridge is driven into its final position. This requires the line to be closed between Dalmuir and Balloch / Helensburgh Central from the end of service on 24 December 2025 until start of service on 2 January 2026.

More project details are available on the Network Rail website.
