Ring IV
Kehä IV ("ring four"; Finnish: Kehä IV, Swedish: Ring IV) is a planned transverse road connection for the Helsinki region, which would serve as a continuation of the current regional road 152 (also known as Kulomäentie). The new connection would continue with the same road number and run west from Tuusula Highway to the north of Helsinki-Vantaa Airport, ending at Hämeenlinna Highway (E12), and from there, the road alignment would continue as the Klaukkala's ring road, the regional road 132.
