GAWLER Council has given its in-principle support to the proposed Tulloch Road/Main North Road intersection upgrade, after receiving concept drawings from the Department of Planning, Transport and Infrastructure (DPTI).
DPTI’s plans show the introduction of traffic lights at the Evanston intersection, as well as the creation of a new single through-lane from Tulloch Road to Morrow Avenue.
Morrow Avenue motorists will not be able to cross the traffic lights onto Tulloch Road, however, as it is set to retain its existing left-in/left-out movements.
According to a report by council’s Infrastructure and Engineering Services manager, Sam Dilena, the through-movement from Tulloch Road to Morrow Avenue was adopted to provide improved local connectivity and safety for motorists wishing to access the residential precinct to the east.
“The potential for rat-running to avoid the intersection at Potts Road, should drivers be wishing to access Gawler East link road or properties north of Coleman Parade on/off of Potts Road, has been considered through the traffic network analysis,” the report stated.
“However, given the dual right turn from Tulloch Road onto Main North Road, and relatively small delays on Main North Road turning left onto Potts Road, combined with the higher grade of road with higher average speed, this rat-run is not expected to generate much appeal.
“The network analysis has forecast that the change in driver routes will not cause any local roads or intersections to reach unacceptable levels of service, or safety.”
The southern end of Barnet Road, meanwhile, will be turned into a cul-de-sac, terminating the existing entry from Para Road/Main North Road. A further concept design for the Barnet Road upgrade – including where kiss-and-drop parking spaces and an emu crossing are set to be established for Gawler & District College B-12 students and parents – will be presented to council at a future meeting.
Council’s support for the Tulloch Road intersection design is subject to community consultation, as well as the continuation of DPTI traffic modelling, once the intersection is operational to determine whether the design fulfils its intent.
Council has also requested that DPTI work with it to implement any subsequent changes, if they’re deemed necessary by this modelling.
