North- and southbound traffic along the length of Leith Walk will be reintroduced during the week commencing 13 February, followed by the electrification of the full line.

Energisation of the line will allow for testing and commissioning to begin, with the first test trams expected on the route at the beginning of March. Final track preparations will also take place in the lead up to the first test tram running.

All tram track, overhead line poles and communications and power ducting has been installed, 93% of the overhead lines are in place and the final section at Picardy Place is being installed over the next two weeks.

Councillor Scott Arthur, Transport and Environment convener, said: “In just a matter of weeks we’ll see test trams running the length of the Trams to Newhaven route, which is really exciting. Energising the overhead lines and buffering of the tram tracks are the final steps before this happens.

“Reopening Leith Walk to two-way traffic is a key moment for the project too and, I’m sure, for all those who live and work in the area. I’d like to thank residents and businesses for their patience and support while we’ve carried out these works.

“Once fully complete, this project will be transformative for Leith Walk and the rest of the route, while benefitting the wider city economy and helping to cut congestion. Not only will it provide reliable, high-capacity connections to the north of the city but has significantly improved and enhanced public spaces and active travel links along the line.”

• Feature: The culture of collaboration driving the trams line to Newhaven

The Trams to Newhaven project remains on schedule for completion by spring 2023 and within the £207.3m budget, with all major construction now complete ahead of the testing and commissioning period.

However, due to industry-wide challenges with the availability of materials and skilled labour, impacted by Brexit and the war in Ukraine along with significant demand for labour in the UK and overseas, there are small pockets of public realm works that will now be completed over the coming months. Full details of the updated programme are available on the Trams to Newhaven website.

A communications campaign has been carried out to remind residents, businesses and stakeholders about the electrification of overhead lines, including safety requirements and permits needed to carry out any work. This work was originally scheduled to take place in October but was re-programmed to allow key infrastructure works to be completed.
