constructions built on the two sides of the highway and above it. The first tutor, heading Bologna, is situated just before the highway exit for Occhiobello. The second tutor, which calculates the average speed basing on the data collected by the previous one, is located just before the highway exit to Ferrara North, instead. Track table A13 Branch Padua South The branch to Padua South links the motorway A13, west of Padua, with the orbital road around Padua itself. The track is flat, with two lanes for each direction of traffic. At first the branch used to make up the A13 ending segment. When the section which leads to A4 was built, the junction created was lacking: actually it was not possible neither getting that branch from A13 heading Bologna, nor getting A13 from the branch heading A4. In 2013 the construction site to build the complete interchange (with the remaining ramps) was opened; the work-in-progress finished in April 2017: the new beltway has been opened to traffic on 20 September 2017. A13 Branch to Ferrara The branch to Ferrara is long and it begins from the A13 interchange Ferrara South. Then it proceeds heading toward Porto Garibaldi uninterruptedly as Beltway 8 for other 49 km. It was opened to traffic on 22 December 1966. This branch is internally-classified as D23 by Autostrade per l'Italia. Furthermore, it is planned an extension (heading west) as far as Rolo-Reggiolo toll booth, on highway A22, realizing the "Autostrada regionale Cispadana" ("Cispadana regional Highway").
