|Route outline (key)|
The B5126 is a short B-road in east Flintshire.
The road starts on the B5129 (former A548) on Connah's Quay High Street. There is a short one-way section here whereby outbound traffic uses Mold Road (the original line of the B5126) and inbound traffic has to TOTSO right then left along what appear to be residential streets to reach the B5129 one block east.
The road heads vaguely westward through the sprawling suburbs of Connah's Quay, not reaching open country for some time. After about the same distance again the road meets the B5125 and quickly crosses the A55. There is a junction here, number 33A, with the A55, although the only possible movement is westbound A55 onto the B5126. The slip road is met just after the bridge.
From this point on the B5126 follows the original line of the A55. It heads west into Northop along Connah's Quay Road before ending at traffic lights on the A5119. Before the construction of the North Wales Expressway (which severed the link) the B5126 ran slightly to the north, along the parallel Church Road, and did not actually meet the A55.
