Oracle Roundabout is a junction on the south side of the Inner Distribution Road in Reading. It is named after The Oracle (or Oracle Riverside), a shopping centre on the north side of the junction. It was formerly known as Southampton Street Roundabout, that street heading south from the junction.


The junction is unusual in that it now has two eastern exits from the roundabout, either side of the flyover. The northern one along Mill Lane is a traditional entry slip to the dual carriageway, albeit now partly in tunnel under The Oracle Shopping Centre. The exit on the south side is one way for A327 and joins London Street further to the east to then head south. Northbound traffic from A327 joins the roundabout using the one way Southampton Street.


The junction was the "southern end" of Stage 2 of the Inner Distribution Road which which was due to be opened on 10 January 1971 (the official opening was to be held on 2 February 1971). This had created a north-south bypass for the town centre. It was originally an at grade roundabout. Contractor was Cementation Construction Ltd..

Stage 3 of the Inner Distribution Road, the Southampton Street flyover, was forecast to be started in 2 years, but did not open until 1986. The flyover and dualling of Mill Lane and Queens Road to Sidmouth Street was due to be opened to traffic on 12 September 1986. The official opening was delayed by the completion of landscaping and took place on 20 August 1987.

It was built as a "traditional" grade-separated Roundabout interchange, but the traffic flows on the eastern side were changed between April 2020 and August 2021 to the arrangement with two exits eastbound and no access to the roundabout for westbound Inner Distribution Road traffic.
