Bus number D20

The D20 bus replaces the common stretch covered by numbers 57 and 157, from Carrer de Collblanc to Passeig Marítim. Numbers 57 and 157 will continue to link Cornellà and Sant Joan Despí with the new Ernest Lluch interchanger. On Avinguda Paral·lel new stretches of bus lane have been marked to speed up the service.
