Masnedsund Bridge (Danish, Masnedsundbroen) is a road and railway bascule bridge that crosses Masnedsund between the islands Masnedø and Zealand (Sjælland) in Denmark.
Together with Storstrøm Bridge it connects Falster and Zealand and was the main road connection between the islands until the Farø Bridges were opened in 1985. It was officially opened on 6 August 1937, and replaced an older railway bridge that was opened on 15 January 1884, and a ferry. The new bridges were commissioned by the Danish state railways (Danske Statsbaner) and designed by them with assistance from Christiani & Nielsen A/S of Copenhagen. Construction was by Dorman Long and company, with Christiani & Nielsen acting as sub-contractors responsible for foundations and reinforced concrete sections. The contract for the work was signed on 13 May 1933.
The bridge is 201 metres long and 8.8 metres wide, with main span of 25 metres. It rests on five piers, with abutments at either end. One of the piers contains the machinery for operating the bascule. Each pier has concrete foundations set into the bed of the sea. A cofferdam was placed around each pier site, before excavating and then filling with concrete. After the base slab had been laid, the cofferdams could be emptied of water and the rest of the pier was constructed. Timber piles were used for the construction of the abutment foundations, and to reinforce one of the piers.
On 12 December 1935 an English steam ship ran into the old Masnedsund Bridge, and destroyed part of it. At that time the new bridge was being built, and it was decided to hasten the building. The railway part of the new bridge was opened on 22 December 1935.
