Brisbane residents want more bridges, with more than 4500 residents letting peak motoring body RACQ know where they want their bridges and who they want to use them.

In May RACQ launched its Bridging Brisbane survey to get feedback on proposed river crossings.

More than 4600 votes were cast for the 12 bridges and tunnels proposed.

The most popular project was the proposed upgrade of the Centenary Motorway to eight lanes. 

RACQ spokesman Paul Turner said the Centenary Motorway upgrade was associated with upgrades along the motorway from Legacy Way outbound to the Ipswich Motorway interchange.

"This received the highest level of support when compared to all of the other options on the table – and it is a project RACQ has been calling for over many years," Mr Turner said. 

The Brisbane City Council had also offered its strong support for this project.

A bridge connecting West End to St Lucia and the Wilson Triple Jump, which would run between the City and Hawthorne, also made the top three most favoured proposals.

Of the 12 projects, the least supported were the South West Tunnel with 48.7 per cent in favour and the Victoria Bridge modifications which had support from 45.2 per cent of respondents.  

The South West Tunnel was a multi-billion dollar tunnel that would have charged a toll and linked the Moggill Road and the Western Motorway interchange with the Ipswich Motorway and Granard Road interchange, while the Victoria Bridge proposal was to modify it to increase its capacity for buses.

Other proposals that gained majority support were a bridge from West End to Toowong, duplication of the Walter Taylor Bridge that connected Indooroopilly to Chelmer, a bridge from Bulimba to Teneriffe, a bridge from Balmoral to Hamilton, a bridge connecting Moggill Ferry Road, Riverview, to where the ferry operates at Moggill Road, a tunnel with a toll linking the Western Motorway and Buranda and a bridge connecting Bellbowrie with River Hills.

Mr Turner said the responses reflected the desire for better infrastructure to combat Brisbane's growing congestion problem.

"Bridges close to the city received good support when providing for all modes of traffic, but similar levels of support were shown for these bridges catering for buses, pedestrians and cyclists only," he said.

"Generally only a small percentage of respondents told us they were against certain options, however, 31 per cent said they weren't in favour of the Victoria Bridge being converted to a public transport only bridge.

"Clearly people want better infrastructure to support their growing transport needs – we'll be highlighting the results to Brisbane City Council and the State Government to ensure this feedback is incorporated in future planning."
