The following represent a brief summary and history of the Merimbula CBD Bypass.
For further information refer to Traffic Study and Council report of 16 March 2010.
Ther Merimbula CBD Bypass has been part of traffic and development planning for a number of years. Traffic studies and public consultatin were underway in 2004.
Traffic study and modelling undertaken based on existing conditions to identify issues and problem areas. The modelling then used to forecast impacts of various possible options.
Results table below of modelling each and combined options with comparisons made via average delay costs in seconds per vehicle.
The option highlighted by red indicates Council adopted option. Council adopted this option with a view to then review traffic modelling results to determine/ ground proof results before considering further upgrade works.

Diagram below shows model predicted traffic flows when CBD Bypass is completed.
For example at the intersection of Beach Street the existing peak hourly traffic northbound is 511 while southbound is 518. This is predicted to reduce to 447 and 430 respectively. Green boxes indicate reduction in traffic flow while red indicates increased traffic flows.
Current intersection design detail. Highlighted property boundary in lower diagram indicates “old mobile” site purchased by Council several years for the purposes of intersection improvements.
