The Expressway is designed as per Asian Highway Standard (Primary Class 'I' access controlled motorways).
The Expressway consists of a dual carriageway with double lane, where total width is 25 m in Hilly Region and 27 m in Terai Road passes through the Terai Plain, Siwalik Range, Dun Valley, Mahabharat Range and Kathmandu Valley. The overall 72.5 Km road stretches from starting point Km 0.0 of Khokana (Lalitpur) to end point Km 72.50 of Nijgadh (Bara District) interconnecting Kathmandu with the East-West Highway.
Flexible Pavement Design has been carried out in accordance with the Pavement Design Guideline, MOPIT, GON which is based on IRC 37 “Guidelines for the Design of Flexible Pavements”. The design life of the pavement has been taken as 20 years. The base and sub-base courses of the pavement have been designed for the full design life.
KTFT Road Project consist of 87 bridges with a total length of 10,596 m which covers 14.62 % of the total length. Total number of bridges comparises 16 special bridges of length 3728m, 49 major bridges of length 6195 m and 22 minor bridges of length 673 m.
Types of Structures adopted are Rigid Frame for Minor Bridges, PSC Girder for Middle and Major Bridges and Free Cantilever Beam for Long Span and High-pier Bridges.
Deck width for different types of formation has been assigned as 2 X 11.30 m for 25 m width, 2 X 11.80m for 27m width and 2 X 13.30m for the bifurcated section at Sisneri.
Preliminary Design of Bridge has been done based on the design load of HS 20・44 or Indian Road Congress (IRC) Class A and Class 70R loading for the road.
There are small, medium and high pier height bridges along the fast track road. These bridges are located in the Terai plain (6 Nos), Siwalik Range (46 Nos), Dun Valley (13 Nos), Mahabharat Range (31 Nos) and Kathmandu Valley (4 Nos).
The Expressway includes 3 Twin Tube Tunnel of total Length 6.415 Km which is 8.85% of the overall length of the Project. The Tunnels have width of 9.5 m and clear height of 5.5 m. The complexity of geological formation, tectonic activities and seismic loading challenges the Tunnel Construction along the alignment.
Mahadevtar Tunnel is the longest tunnel with 3.355 Km length with Horizontal Alignment of R~470m and Longitudinal grade of +0.5% to -2.35 % with arch facing wall portal type in the Mahabharat Range.
Dhedre Tunnel has a length of 1.630 Km with Horizontal Alignment of R~972 m to ~1000 m and Longitudinal grade of -2.35%. arch facing wall has been adopted as its portal type in Siwalik Range.
Lendanda Tunnel has a length of 1.430 Km with Horizontal Alignment of R~820m to 700m and Longitudinal grade of -2.13% with arch facing wall portal type in Siwalik Range.
Three Interchanges are located at Khokana- Kathmandu, Budhune-Makawanpur and Nijgadh-Bara locations. Trumpet Interchange has been designed at Nijgadh where KTFT terminates in Mahendra Highway, which involve at least one loop ramp connecting traffic either entering or leaving the terminating expressway with the far lanes of the continuous highway.
Kathmandu-Terai/Madhesh Fast Track (Expressway) Road Project consists of three Toll Plazas at the following locations:
Provisions for Toll Booth, Administrative Building and Rest Area have been made within the Toll Plaza.
The estimated travel time is 1 Hr 2 Mins along the 72.5 Km Expressway Route. Assuming a diverse mix of traffic on the road, a ruling design speed has been adopted as per the Asian Highway Standard which is 120 Kmph at plain and 60 Kmph in steep terrain.
5 Vehicular Under Pass (VUP), 12 Pedestrians Under Pass (PUP), 1 Pedestrians Over Pass (POP), and 4 Vehicular Over Pass (VOP) have been proposed at different locations.
The EIA for KTFT project was approved in 2015 A.D. The project is fully ensuring that the environmental considerations be the integral part of the construction project during its planning, preliminary design and alignment phases. Significant adverse impacts will be continually examined and efforts will be promoted to achieve a practical and dynamic output in environmental protection and impact mitigation measures.
Road networks make a crucial contribution to economic development and growth and bring important social benefits. They are of vital importance in order to make a nation grow and develop. In addition, providing access to employment, social, health and education services make the road network as a crucial component in fighting against poverty. Furthermore, the KTFT Expressway is considered extremely important due to the following reasons:
KTFT connects Kathmandu, the capital city, with Terai/Madhesh reducing the physical distance between Hills and the Terai Region, within an estimated travel time of 1 Hr. It covers 72.5 km distance from Khokana to Nijgadh better than any other existing routes (eg. 159.66Km from KTM to Birjung through Tribhuvan Highway) for connecting the capital city with Terai.
The vehicles entering the capital city either from Eastern part or the Western part of Nepal has to follow a long route but KTFT Expressway acts as a safer & reliable route for both entry and exit from Kathmandu to Terai.
Drastic reduction in travelling distance and time for reaching Terai from Kathmandu through KTFT expressway helps to reduce enormous amount of fuel consumption which saves millions of dollars every year.
Slow import/export of goods means taking more time that adds additional cost resulting in high prices of the goods. But, once the KTFT Expressway is ready, it will accelerate the import/export activities as it will be the shortest and fastest route to Birjung-Raxaul (India) from Kathmandu. Hence, the frequency of economic movements of people and goods will be very high.
KTFT Expressway of Asian Standard (Primary Class A) having the shortest distance and travel time will help to reduce the maintenance cost and extend the life expectancy of vehicles plying on the road significantly.
KTFT Road Project lies in the North-South Axis of the country. Hence, it could be the transit route between the world's two fastest growing major economies i.e. China and India.
