What will be the extended route for the tram?

Currently, the tram runs from Edinburgh Airport to York Place, and the new line will add 4.69km (2.91 miles) to its length, connecting it to Leith and Newhaven.

Eight new stops will be created, all in keeping with the current look and feel of the existing stops.

In addition to the current stops, people will be able to jump on and off the trams at:

When does the work begin?

The official start date for the construction work was Monday 18 November and the work is now underway on Constitution Street.

The extension is predicted to take around three-and-a-half years, with the aim of having the new line fully operational by Spring 2023.

What areas will be affected?

Constitution Street

Work began in two sections of Constitution Street on Monday 18 November 2019. These are:

- Foot of the Walk to Coatfield Lane – scheduled to be completed by Spring 2021

- Queen Charlotte Street to Constitution Place – scheduled to be finished by Summer 2020.

Throughout this period, access will be maintained from Laurie Street into Kirkgate and from Mitchell Street into Maritime Lane.

Construction work will involve excavation of the road to allow utility diversions, track-laying, installation of tram infrastructure, public realm improvements and heritage and archaeology works.

On Baltic Street, the Robert Burns statue will be removed and restored before being returned once construction is completed.

The 1790s A-listed South Leith Parish graveyard wall will also be taken down and re-built.

Part of this work will include the archaeological exhumation of the remains of approximately 200 gravesites dating from between the 14th and 17th centuries.

According to Edinburgh Council, the work has been "designed to avoid disturbing known burials within the present graveyard."

In order to support public transport provision and pedestrian access, and given the narrow layout of Constitution Street, there will be no on-street parking during construction.

Bus routes will also be disrupted, with Lothian Buses services 12 and 16 operating on diverted routes. Information on changes to bus stops and routes is available on the Lothian Buses website as well as via the Transport of Edinburgh app.

Communal bins previously situated on Constitution Street have been moved to the nearest side street.

Uplifts will be monitored to ensure the area is kept clean and tidy, but if you require a bulk uplift, you should contact Edinburgh Council.

Leith Walk

Enabling work began on two sections of Leith Walk on 18 November. These are:

- Crown Place to Lorne Street

- Pilrig Street to Brunswick Road

During this work, parking and loading bays will be removed on the city bound side of Leith Walk but traffic will continue to flow in both directions, with one lane on each side.

Certain parts of the pavements will be reduced in some locations.

Once these two sections of Leith Walk are completed, works will begin on:

- Lorne Street to Pilrig Street

- Brunswick Road to London Road

This enabling work is expected to be finished in spring 2020 and will create a city bound running lane from Foot of the Walk to London Road, which will remain open for the duration of the main construction works.

The main works will begin in spring 2020, with an estimated completion date of autumn 2021.

Diversion routes and advanced warning signs will be put in place in the vicinity for information and direction. There will be no on-street parking in the areas where construction is taking place.

Bus routes are not expected to be affected, although bus stops may be moved a short distance. Information on changes to bus stops will be available on the Lothian Buses website as well as via the Transport of Edinburgh app.

Some parts of the cycle lane on Leith Walk will be closed during construction work.

Communal bins that are currently situated on Leith Walk in the affected sections will be moved to the nearest side street and the council will monitor uplifts to ensure the area is kept clean and tidy.
