The planning, design and construction of Taiwan's first freeway, National Freeway No. 1, began in 1970 with the task of bringing the rural areas of western Taiwan closer to the cities and encouraging local development along its route stretching from Taipei's northern port of Keelung to the southern port city of Kaohsiung. The opening to traffic in 1978 culminated years of hard work and marked a major milestone in the progress and development of Taiwan's overall transportation network. But, with the ensuing rapid economic development of Taiwan, the demands and burden for this one major arterial became too much for the freeway to handle. The increased standard of living and booming commerce also meant a dramatic increase in the number of vehicles and passengers as traveling conditions on the freeway year by year only became worse and worse; so much so that during holidays and weekends, traffic flow on the freeway at times would come to a complete standstill. In view of this deteriorating situation, the Taiwan Area National Freeway Bureau and related authorities realized not only would Taiwan have to make plans for an additional freeway, but Taiwan would eventually have to establish a more complete and extensive highway network catering to all parts of the island.

By the time plans for the second freeway were under way in 1986 (National Freeway No. 3), the challenges of freeway construction in Taiwan painted a much more complicated picture. With a more affluent and populist society, many new obstacles including rapidly changing attitudes among the people, escalating property values, shortages in workers and labor, unstable gravel and stone prices and problems with the disposal of removed earth made the procedure of getting things done much less smoother than that for the first freeway. Nevertheless, with a combined and concerted effort from all of those involved, a long-awaited and much needed reprieve from the congestion and slow-going on the first freeway was granted when the first segment of the northern section of National Freeway No. 3 was opened to the public in 1993, and other sections and extensions of the freeway were opened to traffic upon their completion in subsequent years. Besides offering an alternative route heading north or south in Taiwan's western corridor, the new freeway offers at least three traffic lanes on each side throughout its length, and a speed limit of 110 km/hr as opposed to the 100 km/hr speed limit of the first freeway.


With these two major north-south freeways in full operation and interconnected by five east-west freeways situated near densely populated areas, Taiwan's drivers and commuters can now be rest assured that the freeway traffic nightmares of the past are just a fading and unpleasant memory, and any township located in western Taiwan is now within a half hour's drive of the highway transportation network.


The topography and terrain of eastern Taiwan on the other hand contrasts sharply with that of western Taiwan. The steep mountainous cliffs running alongside the jagged coast line have made this part of Taiwan much less populated and more of a natural spectacle than a region for expanding commerce and development. Still, with access to such a large area of land being limited to long, winding and often dangerous roads, the main plan is to eventually pave a safe major arterial all the way from the northern capital of Taipei southward towards the southeastern port city of Taitung. To get things started, National Freeway No. 5, traveling a length of 54.3 kilometers from Taipei to the port of Suao and featuring the 12.941 kilometer long Hsuehshan Tunnel, the second longest road tunnel in East Asia and the fifth longest road tunnel in the world, opened to traffic in June 2006.


Throughout its history, CECI has played a major and vital role in the construction of Taiwan's freeways. CECI was the first local consultant to attain experience in the area of highway and freeway engineering when it joined together with other international consultants to carry out the planning, design and construction supervision of National Freeway No. 1. The knowledge and experience gathered from this pioneering project enabled CECI to expand its highway transportation services overseas to other developing countries and built the foundation from which Taiwan's other expressway and freeway projects were born. To meet the needs for transportation in the future, CECI carried out the feasibility study and planning of the second freeway, National Freeway No. 3, in which the quality and effectiveness of the design was a key consideration for its construction. Special attention was given to the freeway designs so as to ensure that the finished freeway would blend in with its surroundings, take cultures and customs into account where possible and present a pleasing appearance to travelers wherever they may be passing through. A number of these sections were designed by CECI, including the landmark Kaohsiung-Pingtung Section, which is highlighted by Taiwan's longest cable-stayed bridge, the Kao Ping River Bridge. CECI has since overseen the construction of these route sections and taken upon the role as engineering consultant for implementing additional east-west freeways, widening the first freeway and planning other freeways in eastern and southern Taiwan so as to fully shape and form a complete and free-flowing highway network which will connect all parts of the island. The triumphant success in carrying out these freeway projects under the close scrutiny of the public and media is a true testament of our dedication and commitment to providing the finest quality of services, and has further cemented our position as Taiwan's leader in highway transportation engineering.
