For its entire length, a narrow verge is maintained, although there is space available for a full width shoulder.

A junction was originally planned for a new development in the Tipner area of Portsmouth, known as the Gateway Project,[1] which was shelved at the time.

In 2005, Portsmouth City Council carried out refurbishments to gantry mounted signs on approach to the M27 junction.

Incorrect lane illustrations, lack of adequate route information, and increased difficulty to read at a long distance lead to driver frustration and confusion.

Due to the regulations regarding junction spacing, the speed limit on the main carriageway of the M275 has been reduced to 60 mph (97 km/h), and 50 mph (80 km/h) on the slip roads and from the southern end of Mile End Road to the Kingston Crescent Junction.
