(ANSA) - TRIESTE, 27 MAR - Heavy traffic is expected along the A4 Venice-Trieste highway for the Easter holidays. Eyes will primarily focus on those returning from their vacations when, in addition to vacationers, tractor-trailers from Central and Eastern Europe will resume their journey. According to Autostrade Alto Adriatico forecasts, the most critical days for travelers will be April 2 and 3, with 'red dot traffic' on the route towards Venice. The freeway authority reports an increase in vehicle flows starting tomorrow morning along the A4 in the direction of Trieste and, from the afternoon, along the route to Venice. This is due to the start of the Easter vacations following the school calendar, the first returns to Central and Eastern Europe of foreign workers, and the mini exodus of tourists to the large cities of northern Italy. Flows will also remain strong throughout the day on Friday and Saturday afternoon, especially in the direction of Trieste. According to forecasts, on Easter Day, there will be a drastic decrease in traffic, which will resume especially from Monday afternoon. The most critical day will be Tuesday, when, starting in the afternoon, heavy vehicles will resume their journeys in addition to tourists. Queues will be possible at the entrance to the Trieste Lisert barrier and near the construction sites for the third lane near Portogruaro. Queues near the construction site will also be possible on the morning of April 3 due to the arrival of more tractor-trailers from Central and Eastern Europe, again towards Venice. (ANSA).
