Arrange the following key historical milestones in Nigeria's transportation infrastructure development in chronological order, from the earliest to the most recent.

- 2Opening of the Port Harcourt to Enugu Eastern Railway segment
- 3Commissioning of the Lagos-Ibadan Expressway
- 4Commissioning of the Abuja-Kaduna Standard Gauge Railway
Cevap
The correct chronological order of Nigeria's transportation infrastructure milestones is: first, the completion of the Lagos to Kano Western Railway line (1912); second, the opening of the Port Harcourt to Enugu Eastern Railway segment (1916); third, the commissioning of the Lagos-Ibadan Expressway (1978); and fourth, the commissioning of the Abuja-Kaduna Standard Gauge Railway (2016).
The correct chronological sequence reflects the historical expansion of transport networks in Nigeria: colonial narrow-gauge rail construction began in the west with the Lagos-Kano line (1912), followed by the eastern coal route from Port Harcourt to Enugu (1916). The post-independence era shifted heavy investment toward motor highways, highlighted by the Lagos-Ibadan Expressway (1978), and transitioned into standard-gauge rail modernization in the 21st century with the Abuja-Kaduna rail line (2016).
