Sheahan Bridge, Road bridge in Gundagai, Australia

Sheahan Bridge is a road bridge that spans the Murrumbidgee River at Gundagai and carries traffic along the Hume Highway. The structure features two separate carriageways designed to handle traffic moving in opposite directions across the river valley.

The northbound bridge opened on 25 March 1977, built by Transbridge as part of a 7.4 km Hume Highway deviation bypassing Gundagai; it replaced the Prince Alfred Bridge, which stood elsewhere. A second bridge by Fulton Hogan opened east of it on 25 May 2009, carrying southbound traffic from December 2009. In July 2026 a replacement for the northbound span was announced.

The bridge is named after Bill Sheahan, the local politician who held the seat of Burrinjuck in the New South Wales Legislative Assembly. Drivers cross it on the Hume Highway bypass that skirts Gundagai, and the 1977 opening was performed by Premier Neville Wran.

This bridge is part of the Hume Highway and allows continuous traffic flow for vehicles passing through Gundagai. Visitors exploring the area will find it serves as an important reference point on driving routes through the region.

The 1977 northbound span was the longest bridge built by the Department of Main Roads at the time, and its 24 southern spans form a viaduct across the Murrumbidgee flood-plain. Road trains were barred from it until March 2021, when use was allowed under permit.
