Maroochy Boulevard Intercgange

Principal: Maroochy Shire Council/Qld Department of Transport and Main Roads

Consultant: Maroochy Shire Council

Location: Maroochydore, Qld

Contract Value: $18,000,000

Completion Date: September 2007

Introduction

The project was managed by Maroochy Shire Council as a joint funding partnership between Maroochy Shire Council and the QLD Department of Main Roads.

The works involved the construction of 2 bridges, (1 crossing live traffic), flexible pavement on and off ramps, stormwater drainage including RCP and RCBC drainage adjacent to live traffic and a wetland area.

The location provided soft ground conditions where rock platforms were required to provide solid foundations on a large proportion of the site. 

Bridgework construction was undertaken in stages to avoid working above live traffic. Part of this construction staging involved the construction of a temporary side track in a confined area adjacent to live traffic on the Sunshine Motorway.
