These works are all being undertaken over weekends in order to minimise disruption

There will then be a series of one day closures on the weekends.

Track improvements are required for the Victoria line upgrade, which when completed, will result in average journey times falling and trains becoming more comfortable, frequent and reliable.

These closures have been planned very carefully to ensure alternative public transport is in place and to try not to conflict with Arsenal football matches.

A full service is running on the Victoria line on Saturday 22 July when a testimonial match is being played.

John Doyle, the Victoria line Manager, said: "The Victoria line upgrade is one of the largest investment projects being undertaken on London Underground over the next decade.

"TfL is investing £10bn to meet London's transport needs, now and in future, with more than half of that being spent on the Tube.

"Track improvements are required for the Victoria line upgrade, which will result in average journey times falling and trains becoming more comfortable, frequent and reliable.

"These works are all being undertaken over weekends in order to minimise disruption as much as possible.

"The extent of work meant that it could not be done in the four hours available in overnight engineering hours when the Tube is not running.

"These closures have been planned carefully to try and avoid Arsenal matches, and with alternative travel arrangements including three rail replacement bus services, two of which will connect with another Tube line, the Piccadilly, and LU tickets will be accepted on local bus routes in the areas affected."

The Sunday only closures starting on 20 August - November are designed to be flexible in response to the Arsenal FC match schedule.

For example, if a match is announced on a Sunday, the closure can be moved to the Saturday of that weekend.

If there are no matches at all, there may be scope for extending the closure to both days.

Full details will be confirmed when the match schedule is finalised.
