When a road is very straight it can be because there is no geographical feature to deflect it, or that there was no local landowner keeping the traffic away from his land. Or, as in this case, because the Romans got here first. This is part of the Icknield Way. As you can see the straight length is not actually great in this case - in fact there are other roads not far away from here that have longer straight runs but are not acknowledged as Roman. However we are nearing the fens and there probably were no topographical features to deflect the road route. At the opposite extreme nearby Cavenham has several sharp corners for no obvious reason.
