KYTC - Extended Weight Coal Haul System

This feature layer represents Kentucky's Extended Weight Coal or Coal By-Products Haul Road System. These road sections had at least 50,000 tons of coal or coal by-products reported as being transported over them during the previous calendar year, as outlined in KRS 177.9771 and KRS 177.979. Public highways that meet specific criteria are designated as part of this system, including state-maintained toll roads, which are always included per KRS 177.9771(1). The Kentucky Transportation Cabinet (KYTC), under KRS 189.230(2), has the authority to set lower gross vehicle weight limits for bridges at risk of catastrophic failure due to excessive loads. Additionally, KRS 177.9771(9) requires the KYTC Secretary to consult with local governing bodies before changing the extended weight haul system. This administrative regulation establishes the road network and related bridge weight limits to ensure safety and infrastructure integrity for heavy coal transportation.本要素图层（feature layer）代表肯塔基州超重煤炭及煤炭副产品运输道路系统（Extended Weight Coal or Coal By-Products Haul Road System）。根据《肯塔基州修订法规》（Kentucky Revised Statutes，简称KRS）第177.9771条及第177.979条的规定，此类路段在上一公历年度内的煤炭及煤炭副产品运输量至少达5万吨。 符合特定标准的公共高速公路将被纳入该系统，其中包括州管收费公路——依据KRS 177.9771(1)条，此类道路始终属于该系统范畴。 依据KRS 189.230(2)条，肯塔基州运输部（Kentucky Transportation Cabinet，简称KYTC）有权针对因荷载过量存在灾难性损毁风险的桥梁，设定更低的车辆总重限值。此外，KRS 177.9771(9)条要求肯塔基州运输部部长在变更该超重运输道路系统前，须征询地方主管部门的意见。 本行政规章旨在确立该道路网络及相关桥梁的重量限值标准，以保障煤炭重载运输的安全与基础设施完整性。
