List of existing and some former crossings of the River Dee downstream of Llyn Tegid (Bala Lake). Upstream of the lake where the River Dee is little more than a stream, there are at least 9 crossings mainly for farm access and forestry. Note that dates for medieval bridges are somewhat subjective given the frequent repairs, rebuilds and widenings.
