The reconstruction project is 562.431m long, the design standard is Class IV highway, the design speed is 20Km/h, and the subgrade width is 4.5m. Five reinforced concrete circular pipe culverts are set. The design elevation of the subgrade profile is the elevation of the road design line. The minimum radius of the convex vertical curve is 400m, the minimum radius of the concave vertical curve is 500m, the shortest slope length is 70m, and the maximum longitudinal slope is 8.5%. Roadway edge line: white solid line, 15cm wide, used to indicate the edge of the motorway. Deceleration yield line: two parallel dotted lines and an inverted triangle, the color is white. The shoulder protection adopts M7.5 mortar masonry M30 block stones. Decentralized overflow drainage is adopted for the crown cross slope, instead of centralized drainage with curbs. There are 5 grade crossings in the whole line, including 1 crossing with grade roads and 4 crossing with substandard roads.

The total length of the reconstruction project is 1683m, the design standard is a single lane Class IV highway, the design speed is 20Km/h (the standard is reduced due to the terrain restrictions in some sections), and the subgrade width is 4.5m. ...... 159 sheets in total

The entry speed of the escape lane is 100KM/H, the longitudinal slope of the braking slope bed is 10%, the aggregate of the slope bed is pea gravel, the length of the slope bed is 164.1m, and the forced weakening device is sand bag, with a height of 2.4m. The design line of the escape lane is the center line of the brake slope bed, with a total width of 10.5m, of which the brake slope bed is 5m wide, the service lane is 4m, the crown cross slope is 2% of the single slope that is high on the left and low on the right, the earth shoulders on both sides are 0.75m, and the cross slope is 3%.

The starting point of the escape lane (braking slope bed) is 0.1m thick pea gravel, which is gradually graded from 30m long to 0.8m thick aggregate. Four rows, eight columns and five layers of sandbags are stacked at the end of the platform. The reinforced concrete guardrail is set continuously, 0.81m high, 0.65m buried in the soil, and the exposed surface is coated with red and white paint. The pavement structure of the section along the slope is consistent with the main line. The left guardrail is 110m long and the right guardrail is 90m long. The longitudinal spacing of pavement drainage pipes is 5m, and the inlet pipe orifice is sealed with gravel wrapped with permeable geotextile. The excavation section is provided with a longitudinal seepage ditch, and the water from the horizontal drainage pipe seepage ditch in the filling section is discharged to the side ditch.

This project is a Class IV highway with a pavement width of 6m and a design speed of 20km/h, and its function is positioned as a collector distributor highway. The design basic wind speed adopted in the design of traffic signs is 30m/s. No part of the traffic signs shall intrude into the building boundary of the highway. The distance from the lower edge of the new single column sign board to the edge of the earth shoulder shall not be less than 2.5m. The reflective material adopts secondary reflective film. The edge line of the carriageway is a reflective hot-melt marking with a width of 15cm and a thickness of 2mm.

The edge line of the carriageway is a reflective hot-melt marking with a width of 15cm and a thickness of 2mm.

The center line of the pavement is generally a yellow dotted line with a line width of 15cm, a thickness of 2mm, a solid line section of 4m, and an interval section of 6m; The yellow solid line is used on the horizontal curve segment with small radius (the horizontal curve radius is less than the general minimum radius); The center yellow dotted and solid line is used within 160m in front of and behind the bridge, and the center yellow solid line is used in the bridge section, that is, the overtaking line is prohibited.

Deceleration vibration marking: it is set at the places where deceleration is required in advance before schools, villages and intersections, and is made of hot-melt materials with a thickness of 4.5mm.
