The Boulevard périphérique de Caen is a ring road circling the French city of Caen. It is the route nationale 814. Traveling speed on the road is limited to 90 km/h (55 mph) between the Exit 13 and 8, with a brief portion near the Exit 1 as well as the Viaduc de Calix limited to 70 km/h (45 mph) and 110 km/h (70 mph) elsewhere. It is a 4-lane hard-shouldered road that was finished on 30 September 1997. The total length of the périphérique de Caen is 26km (16miles).
Notable features include the Viaduc de Calix which spans the River Orne and Canal de Caen à la Mer.
The idea of creating an urban bypass boulevard dates back to 1931 with the Dauger urbanization plan. The plan was a question of improving traffic by organizing peripheral traffic by means of a boulevard connecting radial roads, so as to form a radioconcentric network.[1] It was revived in the early 1970s with the urban development of the city.[2] The ring road was opened in stages:[3]
As of 26 April 2015, the ring road is no longer lit at night except on the Viaduc de Calix and the Bessin and Porte de Paris interchanges.[8]
In order to relieve congestion in the northern ring road, a third lane was planned between the Viaduc de Calix and Le Chemin-Vert. Work began in March 2017 with preliminary tree felling work[9] along the relevant section.[10]
Work on the Hamelin ramp began on 15 April 2021 with improvements on the D60.[11] The construction of the ramp itself was carried out in the second half of 2021;[12] it was commissioned on 27 July 2022.[13]
