Dennis Bridge
Lua error in package.lua at line 80: module 'strict' not found. The Dennis Bridge is a steel truss bridge which carries the Pacific Highway across the Hastings River near Port Macquarie, Australia.
It was opened in December 1961 as part of a project to replace the Blackmans Point ferry across the Hastings River and to bypass Port Macquarie. As well as the Dennis Bridge, this project included a 10 km deviation of the Pacific Highway and a 3 km connecting road from the old to the new highway route (Hastings River Drive).[1]
The Dennis Bridge has a total length of 468 m, and consists of six 37 m truss spans and one 25.6 m truss span, as well as ten steel plate girder approach spans. The deck carries two lanes of traffic and a footway.
Three of the truss spans form a continuous truss, with the central of these three spans (of 25.6 m length) being designed for conversion to a lift span. However this has never occurred.
The bridge was named after Department of Main Roads engineer Spencer Dennis, and is one of a series of steel truss bridges of standardised design erected by the then-Department of Main Roads in the 1950s and 1960s, predominantly across the wide coastal rivers of New South Wales.
