Trinity Bridge or the Triangular Bridge is a unique three-way stone arch bridge that stands at the heart of Crowland, Lincolnshire, England. While it once spanned the divergence of the River Welland and a distributary, the rivers have been re-routed, and it now spans nothing significant.
At Crowland the Welland used to split into two channels, one broadly following the present course of the river, and the other joining the Old South Eau to reach the River Nene near Wisbech. The river no longer flows through Crowland, but the triangular bridge, which spanned the junction, remains in the centre of the town.
