Up to 20 minute delays for Southern Expressway commuters this morning at Reynella SOUTHERN suburbs drivers are being urged to take Main South Rd after lengthy delays caused by duplication works on the Southern Expressway this morning. Nick Green Australian Traffic Network says that Reynella area crews have the roads down to one lane, which is causing delays of up to 20 minutes. A two-car smash on Lower North East Rd and another accident on Port Wakefield Rd, near Lyons Rd, also are slowing traffic.
