During the construction of Phase 3 of the Southern Bridge, or construction of the Zemgale direction magistral traffic interchange, a new motorway – Jāņa Čakstes gatve will be built on the left bank of the Daugava river. The new motorway will connect the Southern Bridge with Ziepniekkalna iela and provide magistral access roads to the Southern Bridge in Pardaugava area. 

There will be two double level access roads at the traffic interchange:the first two level junction from Jāņa Čakstes gatve and Bauskas iela and the second junction from Jāņa Čakstes gatve and Ziepniekkalna iela.
