Construction workers were marking the ground at some sections along the way. The guardrail of the central separation belt was the same as that of the Shi'an reconstruction and expansion section, and the concrete guardrail was used.

"Zhuozhou is 62km, Dingxing is 24km...". The road signs span half the road, and the white words are very conspicuous.

According to the staff of the preparation office for the reconstruction and expansion of Beijing Shijiazhuang Expressway in Hebei Province, in the design of the central separation belt, the service area and interchange section of the whole line are extended by one kilometer on both sides, and three combinations of evergreen plants and flowers are adopted to provide comfortable and natural visual effects for past drivers and passengers.

At the same time, according to the regional cultural characteristics, add landscape sketches, such as Baocang hub section, extract the characteristic landscape of Baoding Zhili governor's office "Baogu stone" as the element, make small sculptures and scatter them in the central separation belt. Jingshi Sign Wall shall be set in key parts. For example, a wall with the content of "Jingji grand passage" shall be set in the section under the Beijing Shijiazhuang Passenger Dedicated Line.

In the roadside design, the berm greening is divided into key sections and general sections according to the geographical location. For example, in the entrance section of Beijing and the boundary section with Shi'an, evergreen trees and colored leaf trees are selected, combined with flowering shrubs, and planted for 5km to create a landscape effect of scattered plant levels.

The greening design of the interchange area enriches the highway landscape by combining the visual focus and creating topographic features. For example, Baoding is interconnected. The terrain is artificially created at the visual focus, and various types of plants such as Pinus tabulaeformis, Begonia and Phoenix tailed orchid are selected. The landscaping technique of reasonable matching of trees, shrubs and ground covers is adopted to create a sense of hierarchy and color.
