Knebworth has the East Coast Mainline running North-south through the village, splitting the village, with the bulk of housing to the west and the services, ships, school, doctor all on the east side. The two bridges in the village are both narrow, with narrow pavement on one side only. it is common for pedestrians to need to step out into the road to pass each other. the bridge near the station is already dangerous, badly lit and of inadequate width. The pavement is not wide enough for a double-buggy for instance. And this is before plans to increase the population of the village.
