English: Flyover under construction, Banbridge bypass. The Banbridge bypass on the Belfast-Dublin road was conceived in the mid 70’s. The land was acquired for a dual carriageway but it was built as a single carriageway opening in 1977. Many northbound drivers were confused and (thinking that they were on a dual carriageway) mistook the wide verge for the southbound carriageway overtaking with fatal results. Despite planting on the verge and oversize “two-way traffic” signs there were still numerous accidents. The additional carriageway was added in 1988. This flyover is under construction at the southern end and another is planned for the northern end.
