Removing a “pinch point” will improve the flow of traffic on a busy road, according to plans submitted to Hull City Council.
The proposal for Wincolmlee would see a disused building demolished to allow the road to be widened by 1.2m (4ft) near the roundabout with Air Street.
According to the application, lorries were “often forced to stop or force oncoming vehicles to make abrupt movements due to the narrowness of the road”.
Drivers had sometimes been forced on to a footpath, putting pedestrian safety at risk.
