A major rebuild of the A206 through Charlton and Woolwich is beginning to reveal its permanent road layout after almost a year of live construction, with new carriageway markings, kerbs, crossings and traffic signals now visible along parts of Woolwich Road and Woolwich Church Street.
London Construction Magazine photographed the corridor on September 2026, documenting how the new layout is being assembled while buses, commercial vehicles, cars, cyclists and pedestrians continue to use the road. The project is not finished: Transport for London currently expects the full Section 2 works between Gallions Road and the Woolwich Ferry roundabout to complete in spring 2027.

LCM Documents the A206 Rebuild Under Live Traffic
The LCM photographic survey records a construction environment that looks very different from a conventional closed highway site. Large stretches remain operational, with temporary barriers and cones separating traffic from active work areas while individual sections are rebuilt around the existing road. Photographs taken along the route show London buses on routes 161, 177 and 180 continuing through the works, together with vans, cars and commercial vehicles. Operatives are visible working within segregated work zones only metres from live traffic. Other sections already show freshly surfaced carriageway, permanent-looking white markings, new kerb lines, traffic signal columns and newly formed pedestrian areas.
The result is a useful snapshot of how a major urban highway project actually progresses. Finished-looking road surfaces can sit immediately beside temporary cones, fenced excavations and traffic diversions because different civil, utility, signal and surfacing packages are reaching completion at different times. This type of road-space coordination is becoming increasingly important across London. LCM has previously examined how TfL's wider London road strategy is changing construction access and traffic management, particularly where works must remain operational around buses, freight and local access.
What Is Being Built Between Charlton and Woolwich?
The works form Section 2 of Transport for London's Cycleway 4 extension. According to TfL's current Cycleway 4 programme, the section runs east from Gallions Road to the Woolwich Ferry roundabout as part of a 2.5km extension between Greenwich and Woolwich. The permanent scheme includes a two-way segregated cycleway along the A206, redesigned pedestrian crossings, new signal-controlled crossings, widened pavements at selected locations, upgraded bus shelters, new planting and Sustainable Urban Drainage Systems. TfL is also installing cycling-friendly drainage gullies to manage water along the redesigned highway.
Several pedestrian crossings are being changed from staggered arrangements to more direct straight-across layouts, including those serving Royal Greenwich Trust School and Windrush Primary School. TfL also identifies new signal-controlled pedestrian and cycle crossings near locations including Mast Quay. The highway investment also sits beside a much larger programme of development between Greenwich Peninsula and Woolwich. LCM's review of what is actually being built at Charlton Riverside shows why the A206 is increasingly important not only as an existing transport corridor but as infrastructure serving future residential and commercial growth.
Why the Woolwich Road Works Have Taken Time
TfL began advance works in summer 2025. Those early operations included removing and installing lighting columns, laying cabling for new traffic signals and carrying out tree works before the main highway reconstruction started in autumn 2025. The route is being delivered as a series of separate work zones rather than one continuous closure. TfL's current programme places the Gallions Road to Stone Lake Roundabout section between September 2025 and December 2026. Stone Lake Roundabout to Eastmoor Street runs through March 2027, as does the section from Eastmoor Street to Woolwich Church Street roundabout.
Further east, some individual work packages have earlier programme dates. This explains why sections can appear substantially finished while barriers remain elsewhere. The overall project completion date remains spring 2027. TfL's live traffic information on 25 September was still listing lane closures on the A206 Woolwich Road between Eastmoor Street and Charlton Lane because of the cycle scheme works. Other restrictions remain around Woolwich Church Street and the Woolwich Ferry roundabout.
Building the New Layout Without Closing the A206
The most striking feature of the project from a construction perspective is the amount of work being carried out without removing general traffic from the corridor. LCM's photographs show lanes repeatedly moving around work zones. Red and white pedestrian barriers, temporary bollards and cones create narrow construction compounds, while traffic is diverted through the remaining carriageway. Temporary signs direct drivers through changing alignments and some parts of the route operate with reduced lane capacity.
This sequencing allows individual sections of kerb, drainage, signal infrastructure and carriageway to be constructed while adjoining lanes remain available. The photographs also show why the work cannot be judged simply by the amount of finished asphalt visible: final surfacing may be complete in one area while signal commissioning, drainage, footways or adjacent junction works continue immediately alongside it. Commercial access adds another constraint. Woolwich Road passes retail parks, builders' merchants, industrial premises, residential buildings, schools and routes serving the Woolwich Ferry. Maintaining access while physically changing lane positions, junctions, bus stops and crossings requires the construction footprint to move progressively along the corridor rather than occupying the full route at once.

Stone Lake Roundabout Is One of the Key Engineering Interfaces
Stone Lake Roundabout is one of the more complex points in the Section 2 design. The project changes the roundabout geometry while introducing new pedestrian and cycling infrastructure and maintaining access to surrounding commercial premises. TfL has published the Stage 1 and Stage 2 Road Safety Audit material for Cycleway 4 Section 2, including Stone Lake Roundabout. The documents form part of the design assurance process for the new road geometry, crossings, visibility and interaction between road users.
Current plans include changes to the central island and a new signal-controlled pedestrian and cycle crossing. Construction drawings also show extensive alterations to kerbs, road markings, footways and adjoining traffic movements. LCM's September photographs add a construction-stage view that design drawings cannot provide. They show the physical compression created by temporary lane layouts and barriers while buses and general traffic continue to negotiate the junction and adjoining approaches.
Tarmac Kier Joint Venture Is Delivering Section 2
Transport for London's published contract register identifies Tarmac Kier Joint Venture as the supplier for Cycleway 4 Extension Section 2 under project reference CW67310. The package was allocated through TfL's Surface Transport Infrastructure Construction framework as a Level 1 direct allocation. The contract register gives an expiry date of 31 March 2027 and places baseline spend in the £25m to £50m band. That figure should not be treated as a confirmed final construction cost: TfL's transparency register reports spend in bands rather than publishing a final out-turn value for the scheme. The distinction is important because the project combines highway reconstruction, drainage, traffic signals, lighting, public realm, crossings, bus infrastructure and traffic management over an extended live corridor rather than a single isolated cycle-lane package.
The New Road Layout Is Already Visible
By 25 September, parts of the permanent geometry were visibly emerging. LCM recorded newly surfaced road sections, new white lane markings, reconstructed pedestrian areas and kerb alignments, together with new signal infrastructure at several locations. Other photographs still show intensive temporary traffic management, with rows of barriers and cones occupying substantial sections of the carriageway. The contrast between the two conditions is particularly clear travelling east towards Woolwich: one section can present a clean new road surface and revised lane arrangement before traffic immediately enters another active construction compound.
The eastern end of the corridor also sits alongside substantial residential development. LCM's recent photographic review of London Square's 700-home Woolwich development shows how the wider district is changing at the same time as the A206 infrastructure is being rebuilt.
What Happens Next on Woolwich Road?
Construction remains active through the autumn and winter. TfL's current programme keeps work between Gallions Road and Stone Lake Roundabout running to December 2026, while the central sections towards Eastmoor Street and Woolwich Church Street continue into March 2027. The next months will therefore move the corridor from the mixed condition recorded by LCM in September, where completed-looking sections sit beside temporary work zones, towards final surfacing, signal commissioning, permanent crossings, drainage, planting and removal of the remaining traffic-management infrastructure. TfL's published target remains spring 2027 for Section 2 as a whole.
LCM field note: London Construction Magazine photographed the A206 Woolwich Road and Woolwich Church Street works on 25 September 2026. Site observations in this article describe only conditions physically visible during that survey and are separated from TfL's published design and programme information.
