A40 London Road Corridor Improvements Project
National Productivity Investment Fund
The project seeks to improve journey time reliability and ease congestion on the A40 London Road through the delivery of a range of improvements including junction changes, introduction of new traffic management technology, bus stop improvements and the optimisation of bus lane locations.
This phase of works is focusing on junction construction and builds on the work already completed to date including improvements already made including new CCTV, refurbishment of all signalised pedestrian crossings, variable message signs and queue detection sensors. The stretch from Easton Street to Loudwater includes junction improvements at the Gordon Road, Hatters Lane, Micklefield Road with Ryemead Way and Gomm Road junctions. When all works are fully completed, it will mean better and more reliable journeys for all who use this key route in and out of the town centre.

Recent Works
Hammersley Lane Junction
The improvement works at this junction to upgrade to the traffic signal equipment allows them to be linked and work in co-ordination with others along London Road, and means the junction will benefit from improved signal timings that are adaptive to traffic flows. The recent work completed in this area involves the installation of new ducting, an upgrade to the traffic signal controller, and the installation of traffic detectors within the carriageway.

London Road/ Micklefield Road/ Ryemead Way/ Cock Lane/ London Road junction
Work has been completed on the northern side of London Road, to the west of the junction. The old kerbline has been removed, new drainage kerbs installed, the footway resurfaced, and the road widened ready for the final layer of new carriageway surfacing which will be completed later in the programme.
Once work on the northern side of the road had been completed, the workforce began work on the southern side of London Road, to the west of the junction. Site clearance works have been undertaken to remove the existing kerbline and footway surfacing, which will allow the carriageway to be widened.

Upcoming Works and Traffic Management
Temporary Traffic Management system being used at London Road/ Micklefield Road/ Ryemead Way/ Cock Lane junction
While the permanent traffic signals equipment and infrastructure around the junction is upgraded, an advanced temporary traffic signals system is being used to replace the permanent signals during their refurbishment. This system will be able to plug in and replicate the existing setup exactly. The temporary system has been put in place overnight this week, and is being installed with temporary signal heads placed next to existing infrastructure in phases ready for switchover from permanent to temporary signals. These signal heads will be connected to existing signal control cabinets by overhead cables as shown in the example pictures below.

Work restarted in July and will continue until October 2020. During construction the following traffic management measures are planned:
- We have analysed the latest traffic flows and have adjusted our working hours to optimise the works whilst minimising any expected delays. The majority of works will be undertaken during daytime working hours (08.00 to 17.00 and 09:30 to 15:30 from 1st September), however it will be necessary for some work to be carried out at night to take advantage of lower traffic flows, such as:
- Decommissioning existing traffic signals and setting up a temporary traffic signal system
- Recommissioning the new traffic signals
- Installation of line markings
- Temporary traffic signals will be deployed for around 6 weeks while the existing traffic signals are refurbished. In order to minimise disruption, these temporary signals will replicate the performance of the existing permanent signals at the junction as closely as possible.
- Lane closures will be in place on the approaches to the junction at various times and locations throughout the works.
- Footway closures will be used throughout the works, with diversion routes in place.
The below table summarises the upcoming phases of work at this junction and the planned traffic management.
