This is the first of a monthly series of posts in which I will track the progress – or not – of London cycling schemes under Sadiq Khan.

Sadiq inherited from us eight major schemes at an advanced stage of implementation, plus one addition to a scheme already open (CS1). All had been designed and traffic-modelled. All had received the support of substantial majorities in formal public consultations. All should have started building – and in some cases finished – last year.

At the date of this post, their status is as follows:

Complete: 0

Under construction: 1

Not under construction: 8

Delays are continuing to increase. In the last month, two already-delayed schemes (Westminster Bridge and the north-south extension) have been delayed further.

A detailed listing is below, ordered by how long it has been since the consultation closed.

Old Street roundabout

Consultation closed: January 2015 (27 months ago).

Public support: 87 per cent said it would improve conditions for pedestrians and cyclists; 63 per cent that it would improve conditions for bus and tube users.

Status: Delayed. Construction has not started.

Cycle Superhighway 1 (City- Tottenham) – Ball’s Pond Road segregated track

Consultation closed: March 2015 (25 months ago).

Public support: 65 per cent (for option B on the Ball’s Pond Road section).

Status: Delayed, possibly cancelled. The segregated track was not opened with the rest of the route in April 2016. In May the then Mayor issued a mayoral direction ordering TfL to begin work on it by October 2016. However, nothing has happened.

East-West Superhighway between Westminster and Hyde Park

Consultation closed: October 2015 (18 months ago).

Public support: 80 per cent.

Status: Delayed but now under construction. Construction of main section, due to start June 2016, began in Feb 2017.

Westminster Bridge roundabout and segregated tracks across bridge

Consultation closed: December 2015 (16 months ago).

Public support: 74 per cent.

Status: Delayed. Construction (due in 2nd half of 2016) has not started. Start further delayed following Westminster terror attack. No new start date given.

North-South Superhighway extension Farringdon St- Kings Cross

Consultation closed: March 2016 (13 months ago).

Public support: 70 per cent.

Status: Delayed. Originally due to start in Oct 2016. Last September, TfL announced scheme approved with start in “spring 2017.” However, it was announced last week that it now “aims” to start constructing “some sections” by “autumn 2017.”

East-West Superhighway extension Paddington- Acton via A40

Consultation closed: March 2016 (13 months ago).

Public support: 71 per cent.

Status: Cancelled.

Cycle Superhighway 11 (Swiss Cottage- Portland Place)

Consultation closed: March 2016 (13 months ago).

Public support: 60 per cent.

Status: No decision. Swiss Cottage gyratory element approved.

Highbury Corner junction scheme

Consultation closed: March 2016 (13 months ago).

Public support: 71 per cent said it would improve conditions for pedestrians and 67 per cent that it would improve conditions for cyclists.

Status: No decision. TfL denied an August 2016 Evening Standard report that the plans had been put “on hold.” However, it appears to be true: a report on next steps promised for autumn 2016 has not yet appeared.

Hammersmith Broadway junction scheme

Consultation closed: March 2016, repeated August 2016 (13/ 8 months ago)

Public support: 79% in first consultation, 73% in second

Status: No decision. TfL website claims that the scheme has been approved and is “set to start” in summer 2017.

However, detailed design of scheme has been handed over to Hammersmith & Fulham Council, who say they have not yet made a decision to to proceed. If approved, construction “could begin in October 2017.”
