Part of Great Titchfield Street to remain closed until late March 2025

Great Titchfield Street between Mortimer Street and Little Portland Street is closed to all motor and cycle traffic until late March 2025 due to carriageway works being done of behalf of Westminster Council.

A diversion is in place directing drivers and cyclists heading westbound through Fitzrovia along Mortimer Street to turn south along Wells Street. But the diversion route is heavily congested with drivers queuing back along Wells Street and Mortimer Street.

Drivers are advised to avoid the area.

The carriageway work is being done as part of Westminster Council’s planned conversion of Mortimer Street to two-way traffic west of Great Titchfield Street, and includes new pedestrian crossings and junction improvements.

According to a notice at the work site the closure of Great Titchfield Street between Mortimer Street and Little Portland Street is to remain until 23 March 2025.

A single lane is now open for cyclists and drivers heading eastbound along Mortimer Street from Marylebone. The single lane opened this week after the road had been closed since mid-July as part of works to convert the street to two-way traffic as part of Westminster Council’s — now abandoned — Oxford Street Programme.

The two-way switch on Mortimer Street is however going ahead and was previously due to be completed before the end of 2024.

However, due to the combination of a weak basement on street, difficulties in installing ducting for TfL signals at the junction of Mortimer Street and Great Titchfield Street and additional utility works, completion will now take place in March 2025, with the two-way switch for both Wigmore and Mortimer Streets occurring together.

A Westminster City Council spokesperson said: “Works on Mortimer Street are ongoing and progressing as planned [sic]. The intention is to complete works with the two-way traffic switch of Mortimer Street by the end of March 2025.”

Westminster Council’s Oxford Street Programme will not proceed further, apart from the Mortimer Street works, due to Mayor of London Sadiq Khan’s announcement that he intends to take control of the street and create a Mayoral Development Area.
