The new 350-metre bridge, which will replace the railway crossing at Fern Street Gerringong, is a key feature of the $329 million Princes Highway upgrade between Mount Pleasant and Toolijoa Road.

The Omega Bridge will link Fern Street with the Princes Highway just north of Gerringong.

Work on the bridge started late last year and it is expected to be opened in early 2015.

The community walk will be an opportunity for people to get a close-up look at the bridge before it is opened to traffic.

The community walk will take place between 9am and noon, starting at Boxsell Oval on Fern Street.

The community can enjoy a sausage sizzle and stalls set up on the oval while people walk across the bridge.

Community members are advised parking will not be available at the oval and free bus services will run from 9am-noon between Gerringong Town Hall and Boxsell Oval. Motorists are advised to park their vehicles in Gerringong.

The project team will also be available on the day to answer questions about the Princes Highway upgrade.

The Omega Bridge was built using a specialised technique known as incremental launching.

This means it was pushed across the railway line with each segment moved forward, allowing space to be made for the next segment to be made directly behind it.

Kiama Council was approached with various names for the bridge, with the naming committee agreeing on Omega Bridge.

The name was suggested by the Gerringong and District Historical Society and some community members.
