The A1434 follows the pre-bypass route of the A46 to the south of Lincoln city centre.
The road starts at traffic lights on the A15 St Catherines, the point where the A15 and A46 met and used to multiplex through the city centre. The road continues south through the suburb of Bracebridge before bearing sharply right to cross the River Witham.
After a few more bends the road joins the Roman Fosse Way and remains dead-straight for the remainder of its route. The B1190 and A1192 are met in quick succession, the second of which requires traffic lights, then the road crosses the city boundary to enter North Hykeham, although on the ground there is no discernible change and functionally we're still in the suburbs of Lincoln.
With the building of the Lincoln Eastern bypass, it is believed that the A1434 will be extended north along the A15. Signs have been put up near the B199 junction showing the road as A1434.
There's a slight detour to a roundabout serving an Asda after which we rejoin the Roman line through what passes for the town centre. The built-up area now starts to get narrower although, owing to ribbon development, the road remains lined with houses until it reaches an out-of-town retail park. On the far side of this the road finally reaches open fields. It's little consolation, however, as the road ends here at a roundabout where it meets the present A46.
Lincoln Eastern Bypass Changes
As a result of the Eastern bypass being built. The A1434 will double in length as it will gain all of the A15 between itself and the A158.
