TfL has appointed CVU Highway Services to undertake the works. This will include the removal of the existing central island planters and the introduction of street trees, a widened bus lane, some repaving work and resurfacing. The plans were set out in the 'Streatham Masterplan' in 2009.
There will be no segregated cycle lane, despite requests from local cyclists. Instead, they will be encouraged to use the enlarged bus lane. A 20 mph limit to improve safety and traffic flow by smoothing the "stop-start" nature of the road, has also been rejected (for details of collisions in previous years on the High Road, including fatalities, see here)
Traffic management measures will be put in place during the works.
The works are scheduled to start on Monday 25 November 2013 and continue for approximately fifteen weeks, depending on weather conditions.
These will be carried out in phases taking place between 7:30 and 15:00, Monday to Friday for works on the southbound carriageway between 10:00 to 17:00 for work on the northbound carriageway.
TfL say they will:
"balance possible disruption to residents with disruption to traffic. Working at off-peak times provides us with the best chance to complete these works safely and as quickly as possible with as little disruption as possible."
"To carry out the work safely, temporary lane closures will be required."
