In terms of key urban construction projects, the urban traffic network has been continuously unblocked, and key projects such as National Highway 110, Zhaonan Avenue, and Provincial Highway S211 have been completed and opened to traffic.

Throughout the year, 20 new roads and 18 parks were built and renovated, 15 "puddle points" on roads and five rain and sewage confluence problems were solved, and the quality of urban infrastructure was greatly improved.
