An exemption allowing buses to use Broad Street is set to be scrapped, while the permitted unloading window for commercial vehicles will be cut by an hour.
Infrastructure Minister Andy Jehan has signed a ministerial decision approving amendments to road traffic legislation, which would formally end bus access to the street.
Broad Street has been closed to most vehicles since 2020, initially as a temporary measure, before being made permanent in 2022.
The move created a pedestrian-focused area in the heart of town allowing only buses, bikes, and commercial unloading vehicles.
However, the original exemption for buses is no longer required after trials of new town bus routes that avoid Broad Street concluded, and a permanent alternative route was adopted.
Reintroducing buses to the street would be “detrimental to ongoing public realm improvements,” a report accompanying the ministerial decision said.
The changes will also further restrict access to commercial vehicles loading or unloading goods between 7am and 10am from Monday to Saturday.
Previous unloading hours were between 7am and 11am from Monday to Saturday.
The revised rules will also apply to nearby sections of Charing Cross and York Street.
Work is underway to turn Broad Street into a pedestrian-priority zone, aiming for completion by the end of 2027.
The aim is to give the area a similar look to the recently completed King Street/New Street crossing.
