|Route outline (key)|
The B5119 is a short B-road in northern Flintshire.
On the far side of the A547 the B5119 is one-way northbound. After a short distance it reaches a T-junction where the mainline TOTSOs left. However, southbound traffic has to bear left where it reaches the A547 under the rocky Graig Fawr, then has to turn right and multiplex to reach the traffic lights. Actually, this route into Dyserth is the 1922 route of the B5119. It originally ended on the A547 (originally B5117) here and was not extended to its current southern end for some years.
Having left Dyserth behind, the B5119 continues northwestwards across the flat coastal terrain of the area. Presently there is a sharp left-hand bend and then the road enters the suburbs of Rhyl and then continues into the centre of town. It crosses the railway line and bears left onto Brighton Road to finish at a T-junction on the A548 one-way system. Because the roads are one-way there is only one direction for B5119 traffic to continue which is dead ahead, on a continuation of Brighton Road. Prior to the construction of the one-way loop the B5119 continued ahead anyway to end on the A525 a short distance further on.
