截至2002年底,河南省的公路里程达到71741公里,高速公路通车里程1231公里,二级以上公路通车里程15847公里。但是,就河南省的整个公路网而言,交通基础设施对整个国民经济的“瓶颈”制约因素还没有得到根本缓解;现有公路上的近万座桥梁,因设计标准低,年久失修,病害累累,成为提升道路技术等级的卡脖子路段。 By the end of 2002, the mileage of highways in Henan Province reached 71,741 kilometers, the mileage of expressways opened to traffic was 1,231 kilometers, and the mileage of highways above Grade two reached 15,847 kilometers. However, as far as the entire road network in Henan Province is concerned, the “bottleneck” constraints of the transport infrastructure on the entire national economy have not been fundamentally alleviated. Nearly 10,000 bridges on the existing highways have low design standards Disrepair, disease, becoming a road to upgrade the technical level of karmic section.
