Connecting terminals: building T1-T2 connecting road
To ensure on-time movement for passengers traveling between Terminal 1 and Terminal 2, a 3.87-km

connection road was constructed within the airport. The road was designed with a width of 18.5 meters
(4 lanes, 2 in each direction) and included the construction of 2 underpasses (955 meters in total) and one
bridge (49 meters). This reduced travel time by 25% from 19 minutes to 14 minutes. The road construction
took place from November 2019 to April 2023.

Building new road: constructing T1 southern connecting road
The southern connecting road near Terminal 1 was built to address issues with the existing road. The
original road had 3 consecutive signalized intersections, which disrupted timely travel between terminals.

To solve these issues, a new southern connecting road near Terminal 1 was constructed. Due to cost-saving
measures implemented after the COVID-19 pandemic, the final length of the southern connecting road
was set at 0.97 km. Construction began in November 2022 and was completed in February 2024. Although
the road was shorter than initially planned, all the original project objectives were achieved. With the new

road, the travel distance between terminals was reduced from 19 to 16 km, cutting travel time by up to 5
minutes.

Creating connections for MRO: building roads for the MRO Complex
A new 2-km access road was constructed to connect the MRO Complex with the passenger terminal’s
connection roads. The road's cross-sectional width was carefully determined to accommodate the
characteristics of vehicles transporting aircraft and other equipment. To handle the anticipated increase in
future traffic, the access road was designed as a 4-lane, 2-way road.

The internal roads within the complex were also planned and constructed with 4 lanes to ensure smooth
vehicle flow and traffic safety. Additionally, 3.5-meter-wide extra lanes were included on each road to
facilitate vehicle entry and exit from individual lots within the complex.
Given that cargo trucks traveling within the aviation complex often transport large items like aircraft

engines, the lane width was set at 3.5 meters to accommodate such loads comfortably. Moreover,
pedestrian and bicycle paths were constructed along both the access road to the complex and internal roads
to ensure continuous routes and smooth traffic for cyclists and pedestrians.
