?Taipei, March 16 (CNA) Traffic controls will be enforced on the nation's freeways over the four-day Tomb Sweeping Festival in early April, the National Freeway Bureau said Monday. Traffic control measures will be in effect at entrance ramps to limit the number of vehicles accessing the freeways from April 3-6 and tolls will be suspended between 0:00 am and 5:00 am during this period to encourage motorists to get on the road when there is least traffic, according to the bureau. A unified rate of NT$0.9 (US$0.03) per kilometer will be adopted during the holiday period, a 25 percent discount on the standard rate.? Motorists traveling between the Hsinchu and Yanchao interchanges on National Freeway No. 3 will receive an additional 20 percent off.? However, the standard toll-free first 20km of travel on all freeways each day will be suspended during the holiday, the bureau said. As many as 2.8 million motorists could use the freeways per day during the period, it added. In an additional efforts to ease congestion during the extended weekend, the bureau plans to introduce a separate plan offering motorists a 20 percent discount from March 28-29. The bureau said it hoped the measure, to be implemented on all freeways during the preceding weekend, will encourage the public, where possible, to travel in advance of the holiday rush and do their tomb-sweeping a week early.
