High-Street Avenue-8 Banner Description
We are investing over £2 million to upgrade the electric network in the heart of the city, enhancing the reliability of power supplies for thousands of residents and businesses in the central district.
We need to remove an outdated substation from beneath one of the entrances to the main shopping mall on High Street – and construct a new one next to the public library on Maple Avenue. Following this, we will connect our new substation to the existing mains.
We will be working from 1st August for approximately 20 weeks, until 20th December.
We will start by digging exploratory holes around our work site to map the exact location of our mains and identify the positioning of other utilities such as water, gas, and telecommunications.
We will also build our compound in the Maple Avenue parking lot to store materials and provide a welfare area for our staff. We will ensure that the rest of the parking lot remains open, albeit at a reduced capacity.
After the exploratory phase, we will commence the clearing and preparation of the space for the new substation. This includes digging trenches along High Street and Maple Avenue to lay the new mains.
Once we have connected our new substation to the electric network – we will safely decommission and remove the old one.
As we complete each segment of the project, we will restore the road and clean up the site, removing all materials and equipment.
There will be no need to interrupt anyone’s power supply during the execution of these works.
We need to carry out these essential works before the winter – and to do this safely we need to close some roads, introduce diversions and suspend some parking bays.
To connect the new governor, we will close West Green Road from the High Road entrance to the junctions with Westerfield Road and Portland Road from 7th May until 21st July.
This means there will be no vehicle access to West Green Road from Westerfield Road and Suffield Road. Both roads will remain accessible from Seven Sisters Road and a two-way system will be in operation for the duration of the works to allow vehicles in and out.
Parking bays at the top of Suffield Road will be suspended – including the EV charging points. This is to allow for delivery vehicles to get close to West Green Road and have space to turn round.
Portland Road will remain open to vehicles turning left from West Green Road, and a traffic light system will be in place for the duration of the works.
Seven Sisters Station bus stop E (West Green) and D (High Road) will also be closed, and bus routes 41 and N41 will not serve stops between Spur Road and High Road. These buses will follow a diversion route along Phillips Lane and the High Road before continuing their normal route along Broad Lane.
Around half of the bays in the Westerfield Road car park will be suspended while we are working. The exit near West Green Road will be closed, and the entrance will be widened to become a two-way entry and exit point. Some parking bays opposite the entrance will be closed to make it easier for vehicles to get in and out.
LTN camera-controlled enforcement will be temporarily suspended on the following roads for the duration of the works:
We work closely with Transport for London and Haringey Council to agree all our traffic management plans. You can find more details on the traffic management plans HERE.
