Previously, traffic could travel along the whole route in the direction of town, with the exception of Don Road along the east of Howard Davis Park.

However, after the opening of the Tunnel in the 1960s, there was a desire in the States to reduce the amount of traffic travelling through the town centre.

The first part of the route runs from Grenville Street to Weighbridge along a one-way single-lane road.

The remainder of La Colomberie was pedestrianised in the 1990s, interrupting the traffic flow from the East to the Town Centre.

The road runs through Longueville over a hill to Grouville Church and further onto Gorey.
