Further on in the parish of Stainton by Langworth, near Rand Wood, the B1399 heads north-east while the A158 changes direction and heads east to Wragby. In Bullington it passes Bullington Hall and in Rand, it passes Brown Cow Farm, and there is a left turn for Rand and Rand Farm Park. The Rand Group construction company was based there until October 2009 when it went into administration. It is briefly the parish boundary between Rand, to the north, and Goltho, to the south, and passes Goltho Gardens, with a teashop. Approaching Wragby it enters East Lindsey. Here it crosses the B1202 at traffic lights near the Turnor Arms then forks with the A157 which heads through the Lincolnshire Wolds to Louth. The A157 formerly followed the A158's current route to Lincoln, and the A158's western terminus was at Wragby before the 1940s. It passes the parish church of All Saints, and crosses the former Louth to Bardney Line. From here the route gets quite twisty then heads south-east around the south end of the Wolds. It crosses Stainfield Back at Langton Bridge, and passes through Langton by Wragby, where there is a left turn on a bend for Panton, then a right turn on a bend for Chambers Farm Wood, part of the Lincolnshire Limewoods nature reserve. At Hatton Bridge, it is the parish boundary between Langton by Wragby, to the west and Hatton, to the east.
