[2][3] From a roundabout with the Tasman Highway outside Sorell the highway runs northeast to another roundabout roughly housing its former alignment inside Sorell, crossing Iron Creek before turning south-east to Forcett.

From there it continues in an easterly direction, crossing the Carlton River, to Copping, where it turns south to Dunalley.

After following the southern shore of Eaglehawk Bay to the west the highway turns south and continues in that direction to Port Arthur where it transitions to route B37 (Nubeena Road).

[7] The Denison Canal opened in 1905 with a wooden, manually operated swing bridge.

This allowed traffic to bypass Sorell[9] instead of going right through the town on Tasman Highway or using Parsonage Place (to which was applied a 5-tonne limit, despite accompanying stop-gap improvements and a rename).
