Designated traffic lanes will be set aside on Beijing-Chongli Expressway for smooth traffic flow during the upcoming 2019 Beijing International Horticultural Exhibition, the capital's transport authorities said on Monday, Beijing News reported.

The expo, which will kick off on April 29 and run until Oct 7, is expected to attract 16 million visitors from home and abroad.

The special lanes will be put in use on weekends and national holidays (Labor Day, Dragon Boat Festival, Mid-Autumn Festival and National Day) during the horticultural exhibition, according to Beijing Municipal Commission of Transportation.

While the special lanes are in use, only public transport vehicles, large passenger cars, certified Beijing Expo vehicles, road maintenance vehicles and emergency vehicles, such as police cars, firefighting vehicles and ambulances, will be allowed to run on these lanes.

The restriction applies to vehicles traveling out of Beijing between 7 am and 11 am and to those entering the city from outside Beijing between 5 pm and 10 pm. Violators will be fined 100 yuan.

Also part of support measures for visitors to the event, construction of 11 temporary parking lots was completed earlier this month. The parking lots, with a total area of 106.04 hectares, can accommodate more than 20,000 vehicles.
