According to the pre-feasibility study report, these projects have a total length of 36.5km, of which about 16km of elevated roads will be built to increase transport capacity.
The total investment is estimated at VND60,000 billion, with the state budget participating from 50% to 70%. The remaining capital is mobilized by BOT investors through equity and bank loans.
The consultant proposed applying many toll collection scenarios, in which vehicles using the elevated, high-speed lanes will be subject to higher tolls. Meanwhile, vehicles traveling in the lower lanes will be subject to lower tolls or free of charge. The toll collection method is considered between fixed-trip tickets and distance-based tolls.
National Highway 13 (from Binh Trieu Bridge to the border of Binh Duong province) is nearly 6km long, and is proposed to be expanded and built with a 3.7km elevated road with 4 lanes. The parallel road below has 3 lanes on each side.
The total investment capital is nearly 20,000 billion VND, of which BOT capital is about 5,986 billion VND (30%), the rest is from the budget. The proposed fee is 44,200 VND/trip for the elevated lane, 1,400 VND/km for the low-lying road, with a payback period of about 23 years.
National Highway 1 (from Kinh Duong Vuong Street to Long An province border) is 9.3km long and is proposed to be widened to 60m to accommodate 10-12 lanes.
Total investment capital is more than 15,800 billion VND, BOT capital is about 5,462 billion VND (33%), the rest is from the budget.
Three toll collection scenarios were proposed: If the toll collection is for all 8 express lanes and the 4 parallel lanes are free, the payback period will last 25 years and 1 month; if the toll collection for all parallel lanes is equal to 45% of the express lane, the payback period will be more than 19 years; if the toll collection for the parallel lanes is equal to 65% of the express lane, the payback period will be reduced to more than 18 years.
The North-South axis road (Nguyen Huu Tho street) from Nguyen Van Linh intersection to Ben Luc - Long Thanh expressway has a total length of 8.6 km, with a proposed 7.8 km of 4-lane elevated road, while the parallel road below has 3 lanes on each side.
The total investment capital is about 8,483 billion VND, of which BOT capital is about 6,304 billion VND (74%), the rest is from the budget. The toll for the elevated road is 52,000 VND/trip, for the regional road is 2,100 VND/km, with a payback period of about 23 years.
The 3.6 km long Binh Tien Bridge is proposed to be built entirely elevated, 30 to 40 m wide, connecting District 6, District 8 and Binh Chanh District.
The total investment capital is about 6,800 billion VND, of which BOT capital is about 3,458 billion VND (50.38%). The proposed fee ranges from 32,658 VND to 125,607 VND/trip depending on the type of vehicle, with a payback period of more than 15 years.
National Highway 22, the 8.7km section from An Suong intersection to Ring Road 3, will be expanded to 10 lanes, with a total investment of about VND8,400 billion, of which BOT capital is about VND3,541 billion (40.19%).
The high-speed lane is expected to collect a toll of 2,100 VND/km, the intersection lane will collect 1,400 VND/km, with a payback period of about 18 years and 7 months.
