In March 2016 (ten years after the previous redevelopment), talk of the redevelopment of the Sir Bobby Charlton Stand re-emerged. In order to meet accessibility standards at the stadium, an £11 million investment was made into upgrading its facilities, creating 118 new wheelchair positions and 158 new amenity seats in various areas around the stadium, as well as a new purpose-built concourse at the back of the Stretford End. Increasing capacity for disabled supporters is estimated to reduce overall capacity by around 3,000. To mitigate the reduction in capacity, various expansion plans have been considered, such as adding a second tier to the Sir Bobby Charlton Stand, bringing it to a similar height to the Sir Alex Ferguson Stand opposite but without a third level and increasing capacity to around 80,000. Replication of the corner stands on the other side of the stadium would further increase its capacity to 88,000 and increase the number of executive facilities. Housing on Railway Road and the railway line itself have previously impeded improvements to the Sir Bobby Charlton Stand, but the demolition of housing and engineering advances mean that the additional tier could now be built at reduced cost.
