|Route outline (key)|
The B1178 is a rural B-road south of Lincoln.
The road starts at traffic lights on the A607 to the east of Harmston and heads east across Harmston Heath to reach the A15. There's then a multiplex north along that road for over a mile until the B1178 regains its number by RAF Waddington. The road heads east, away from the airfield.
The road is fairly straight, although there is a sharp left-right turn as we start to cross Potterhanworth Heath. The B1188 is then crossed at a staggered crossroads, after which we go under the Peterborough to Lincoln railway line. The road soon enters Potterhanworth, where it ends at a T-junction on the B1202.
The B1178 was originally unclassified but came into existence in the 1940s. Originally it started on the A607 in Waddington and headed due east over the A15 to its present eastern terminus. However, this route was short-lived.
RAF Waddington was built on top of the western section of the B1178 during World War II, severing the route. Later maps show a Class II road heading east out of Waddington and ending at the airfield boundary. It was not until the late 1950s that the road was given its current route round the south side of the airfield, thus creating the lengthy multiplex along the A15.
