After another one and a half kilometres (0.93 mi), the route veers to the north-east, and there is a trumpet interchange connecting to the bypassed section of Midland Highway.

Skirting around the developed area of Brighton, the bypass crosses the Jordan River, and curves back to the north to a diamond interchange with Tea Tree Road.

The Southern Railway Line had become outdated due to years of poor maintenance and was no longer an efficient alternative to road transport.

The bypass is designed as a fully grade separated Dual carriageway Highway from the Bridgewater roundabout to just north of Pontville.

Completion of the bypass also facilitates a seamless connection to the Brighton Transport Hub and provided an opportunity in its construction to realign the south line in certain sections.

[12] The Brighton Bypass remains controversial because of the Tasmanian government's refusal to properly investigate the proposed road corridor for Aboriginal sites prior to construction.

[14][15][16] Local Aboriginal activist Michael Mansell called for the bypass to be scrapped stating that to continue "would be cultural vandalism, on an extreme scale".

[18][19] In March 2010, with construction well advanced an archaeological excavation of the Jordan River Levee uncovered stone tools dating back more than 30,000 years.

[26] The Aboriginal community then released an amended plan proposing to have the highway cut through the southern tip of the Brighton Suburb.

[30] The report's key findings stated that the alternative bridging options would increase the overall cost of the bypass by at least $127 million and delay its completion by up to 4 years while new planning and environmental approvals were sought.
