The $786 million, four-lane Bridgewater Bridge has been opened to the public after more than two-and-a-half years of construction, with thousands of people registering to cross it on foot for the first time. It has been spruiked by the state government as the largest transport infrastructure project in Tasmania and replaces a steel lift bridge built more than 70 years ago. The bridge will open to road traffic on Monday morning, and landscaping and construction works will continue at the site over coming weeks.
