Accordingly, the section of National Highway 1A through Vinh City is renovated and upgraded with the route from Km459+930 - Km463+570, length 3.64 km, starting from Quan Bau intersection to the end point at Vinh market intersection. The project includes 3 streets: Mai Hac De 1.132 km, Le Loi 1.161 km and Quang Trung 1.159 km.
To repair and upgrade, relevant parties and Vinh City People's Committee surveyed and prepared project documents.
Of which, Mai Hac De Street and Le Loi Street currently have a roadbed width of 45 m (road surface width in both directions is 18 m, median strip is 1.5 m wide, sidewalks on both sides are 25.5 m wide).
Quang Trung Street has a roadbed width of 56 m (road surface width of 18 m, median strip width of 1.5 m, sidewalks on both sides of the road 36.5 m wide). After more than 10 years of exploitation and investment in repair, the asphalt concrete road surface has shown local damage, the road surface is cracked and the asphalt concrete is peeling off.
Therefore, Road Management Area II and Vinh City People's Committee propose 2 options, specifically as follows:
Option 1: Expand the non-motorized lane into a 4-meter wide mixed lane on each side, ensuring a cross-sectional area of 4 motor lanes and 2 mixed lanes, reorganizing intersections, and simultaneously reinforcing the entire road surface with asphalt concrete.
Specifically, Mai Hac De Street and Le Loi Street will maintain the existing roadbed width of 45 m, cut and widened to ensure a road surface width of 18 m. m and expanded by 8 m (each side expanded by 4 m); median strip expanded from 1.5 to 2 m wide; sidewalk narrowed to 21 m (each side 10.5 m wide).
For Quang Trung Street, the existing roadbed width of 56 m will be maintained, the road surface will be widened to ensure the current surface width of 28 m and expanded by 8 m; the median strip will be widened from 1.5 m to 2 m; the sidewalk will be widened to 32 m (16 m on each side). The budget for the roadbed, road surface, curb, and curb items is estimated at about 57.54 billion VND from the road economic activity budget.
Option 2, as proposed by Vinh City People's Committee: Expand the road surface by 2 more lanes for motor vehicles, 3.5 m wide on each side, ensuring the cross-sectional scale of 8 lanes for motor vehicles, 2 lanes for non-motor vehicles, reorganizing traffic at intersections, and at the same time, reinforcing the entire road surface with asphalt concrete, ensuring compliance with the Planning approved by the Prime Minister in Decision No. 52/QD-TTg dated January 14, 2015.
Accordingly, for Mai Hac De and Le Loi streets, the existing roadbed width will be kept at 45 m, expanded to ensure the current road surface width of 28 m and expanded by 5.5 m (each side will be expanded by 2.75 m); the median strip will be expanded from 1.5 to 2.5 m; the sidewalk will be 9 m wide.
For Quang Trung Street: Maintain the existing roadbed width of 56 m, expand the road surface to ensure the current surface width of 28 m and expand by 5.5 m (each side expands by 2.75 m); median strip 1.25 m: sidewalk width 20 m (each side 10 m).
Implementation budget: For the items of roadbed, road surface, border ditches, curbs, about 104.7 billion VND from the budget for road economic activities. For the items of upgrading, renovating sidewalks, relocating the electrical system, replanting trees, undergrounding, and longitudinal ditch systems, the budget is about 345 billion VND from the Vinh city budget.
In a document sent to the Road Management Department, the representative of Road Management Area II said: The reason why the Management Area agreed with the Vinh City People's Committee to propose the Road Department the above 2 options is based on the current conditions and the actual survey of the sidewalk width of the sections which are still quite wide (12.75 m for Mai Hac De Street, Le Loi Street and 18.25 m for Quang Trung Street) while the road surface is only arranged with 4 lanes for motor vehicles and 2 lanes for non-motor vehicles, so it cannot meet the traffic volume during rush hours. This is a national highway along the North - South axis, passing through the center of Vinh city, with a very large traffic volume, diverse types of vehicles, from bicycles, motorbikes and especially cars, so it often causes traffic jams during rush hours, from 6-8 am, from 11-2 pm and 4-6 pm every day.
