08:00 to 18:00 Monday to Friday until early April 2018

The A100, Byward Street/Tower Hill will be reduced from two to one lane westbound from Tower Hill Garden to the junction with Great Tower Street.

Early April to summer 2018

At all times, the A100 Byward Street/Tower Hill will be reduced from two to one lane westbound from Tower Hill Garden to the junction with Great Tower Street.

If you are travelling westbound during morning peak times (07:00-10:00am) you are likely to experience delays of 10 minutes on your usual journey time. You may wish to consider travelling outside of these times or choosing a different route to avoid extra delays to your journey.

For eastbound traffic, provision will remain the same with a single lane remaining open.

Access to Trinity Square will be maintained for the majority of the works; however, a temporary closure will be needed. There will be no access between Trinity Square and Byward Street/Tower Hill from late May to mid-June 2018. A signed diversion will be in place.

There will be some overnight road closures for resurfacing.

For the latest information on traffic conditions, see our traffic status updates page or follow @TfLTrafficNews on Twitter.


Bus route 15, RV1 and N15 will continue to serve Tower Hill and stop at all regular bus stops. However, delays of up to 10 minutes are expected to affect all traffic so please plan ahead and allow more time for your journey.

For the latest information on how buses are running, see our bus status updates or follow @TfLBusAlerts on Twitter.


The lane closure will make surrounding roads busy. Contact your coach operator for details about possible changes to services, and allow plenty of time to travel.


Access to the Cycle Superhighway will be maintained for the majority of the works, however, some closures will be needed. It will be closed temporarily near Trinity Square in May 2018 and during some overnight closures for resurfacing. A signed diversion will be in place.

Why this is happening

As part of works to introduce segregated cycle track for the East West Cycle Superhighway along Byward Street/Tower Hill we signalised the junction of Byward Street/Tower Hill and Trinity Square. Initially, left and right turns into Trinity Square were restricted at the junction.

Following community feedback, in April 2016, an interim scheme at the Trinity Square junction allowed left turns into Trinity Square from the A100, Byward Street between 21:00 and 05:00.

This will now be made permanent, with the left turn permitted for all vehicles at any time. As part of the works, we will be relocating traffic islands and resurfacing the carriageway. We expect the scheme to bring about improved traffic journey times.
