The first traffic has travelled over the new Port Road bridge at the intersection with South Road – another major milestone in the North-South Corridor, Torrens Road to River Torrens Project.

The new northbound surface road on South Road was also completed between Port Road and Henry Street.

The new bridge will also pave the way for the next stage of the project’s ‘big dig’ – the excavation of 350,000m3 of material to enable the construction of the 3km non-stop lowered motorway.

The Port Road bridge is made up of:

*             66 x 0.9m diameter piles

*             23 x 30.2m long concrete beams, weighing between 57 and 64 tonnes per beam

*             2,760m3 of concrete

*             580 tonnes of steel reinforcement

*             7,000m3 excavation

*             2,000m2 bridge deck

It’s the second bridge to open as part of the $896m project with the Grange Road bridge opened in November. Both bridges have been delivered ahead of schedule.

The excavation under the Port Road bridge is expected to be completed by mid-2017.

The bridge deck pour used 2,760m3 of concrete and 580 tonnes of steel reinforcement using high quality billet from Arrium, Whyalla.

More information on the project is available from the T2T Alliance website.
