Barnicle Street Boat Ramp

Project Description / Overview:

Queensland Department of Transport and Main Roads (TMR) have identified that Townsville is short of recreational boating launching and retrieval facilities for all-tide access.
TMR have commissioned Townsville City Council to upgrade the old ramp at the end of Barnicle Street, Railway Estate, approximately 150m downstream of the newly constructed ramp to assist with meeting the demand. The Queensland Government is funding the work.
Reconstruction of one half of the ramp is needed to meet the TMR standard, while the other half requires an extension to achieve the lowest astronomical tide(LAT) level. Minor patching of the shoulder embankments is also required.

Client:

TCC on behalf of Transport & Main Roads
