The Huon Highway section adjacent to the Kingston Wetlands reopened slightly early on Thursday afternoon, August 11.
The road had been closed between the Channel Highway and the Huon Highway roundabout to enable a pedestrian underpass to be installed.
Works are scheduled to continue at the site for another six to eight weeks, with temporary traffic management conditions in place, whilst remaining work is completed.
Kingborough Council said the principal contractor, DCS Civil, has completed a significant amount of work during the road closure period, reducing the expected timeframe for construction.
Road users are requested to continue to follow the signage and drive carefully through the area, for the safety of the construction crew.
Council has thanked the community for their patience during this time.
