Much of the attention so far has focused on the most controversial issue - whether the northern section of the route should use the Roseburn Path, a former railway line which is now a popular pedestrian and cycle path, or go via Orchard Brae, which would mean crossing the Dean Bridge, seen as a major engineering feat.
However, the Roseburn Path v Orchard Brae debate covers only part of the route.
The new line heading south from the city centre, along the Bridges corridor to Cameron Toll and then towards the Infirmary and BioQuarter, with the possible extension to Shawfair and elsewhere, has been rather neglected so far.
Yet there are challenges and consequences here too - a tight turn onto North Bridge which could mean narrowing a pavement on Princes Street; but measures on South Bridge which would allow pavements there to be widened; residents who may face restrictions on turning in and out of their drives because of overhead lines down the middle of the road; and extra congestion causing delays.
So here is a step-by-step guide to what is in store along the route of the proposed new tramline from Granton - including both Roseburn Path and Orchard Brae options - all the way to the Infirmary.
The proposals are currently out to consultation until next Monday, November 17.
17. Old Dalkeith Road
Beyond Cameron Toll, the route is largely on-street along Old Dalkeith Road, mitigating potential impacts at Bridgend Farm, and wider tree loss along the route. | Google
18. Little France Drive
Little France Drive, close to the Royal Infirmary and Bioquarter, includes a segregated corridor for trams. The route then turns right to run adjacent to Tobias Street and then right again to follow the A6106 to Shawfair. These sections are also expected to be largely off-street, although the details will be agreed with Midlothian Council at a future stage. | Google
