HS2 shares exactly when and where construction will happen in London over next three years – My London
The High Speed 2 project has released all its construction plans for the next few years, including where building works will take place and when they are expected to happen.
The new HS2 Corporate Plan first covers the concrete parts of the project then moves on to the mechanics and electrical parts.
Phase One of the project is the link between London and Birmingham, which will open between 2029 and 2033.
It’s 140 miles long and consists of just four high speed stations, according to London site IanVisits.
According to the report, there’s quite a few stages of the project to come.
Starting in September 2020, here’s everything planned in the next few years for the project.
