Department of Bridge and Tunnel Engineering has set the undergraduate major, Road, Bridge and River-Crossing Engineering, and has nurtured senior talents of engineering techniques for the highway traffic system, city construction system and railway construction system.

At present, there are 17 professors in this department, among which there are 3 titled as professor and doctoral supervisor, 1 as overseas part-time doctoral supervisor, 9 as associate professor and 7 as assistant professors. Plus, among the teachers, 11 of them own the doctorate (including 5 post-doctors) and 2 of them are PhD candidates. Above 50% of the whole teaching staff have the experience of visiting high-level universities abroad for over 1 year. The subject of bridge and tunnel engineering has opened a post-doctoral research station for its subject direction, and has owned the degree-awarding right for Doctor of Engineering, Master of Science in Engineering, Master of Engineering and Bachelor of Engineering, also has been a national first-class civil engineering key subject.

 The main research topics of this department focus on structural durability of bridges, wind-resisting and seismic design of bridges, application of new materials to bridges, theory research of composite structure of bridge, assessment and reinforcing technology of existing bridges, design theory and construction technique of externally pre-stressed concrete bridge, structural health monitoring of long-span bridge.
The subject of bridge and tunnel engineering has been actively participating in the national and local economic construction, widely connecting the highway traffic and municipal construction system of provincial government of the whole nation especially the northeastern region, solving plentiful problems for the infrastructure construction of highway traffic. In the meantime of participating in engineering projects, this subject emphasizes the research of basic theories, and has been committed for 7 projects of NSFC (Natural Science Foundation of China) and 3 Doctoral Scientific Fund Projects of Ministry of Education in recent five years. As a first participating unit, it has accomplished the compilation and revision of 5 volume of bridge specification of Ministry of Communication and has collectively completed 3 western transportation construction projects of Ministry of Communication and over 80 provincial and local scientific research projects.

International Exchange
The strategy of international schooling is implemented by the department of bridge and tunnel engineering, yearly with professors visiting abroad for further study sponsored by Chinese Scholarship Council and regularly attending international high-level academic conferences in group. Some overseas sophisticated professors are hired for short-term lectures at our school, improving the foreign communication ability of our teachers.Relying on the project of nation-sponsored graduate students, the most outstanding ones are selected to study further well-qualified mentors of top-level majors and schools abroad like UCB (University of California, Berkley), UIUC (University of Illinois at Urbana-Champaign), NU (Northeastern University), UCLA (University of California, Los Angeles), VT (Virginia Tech), Rice University, etc., developing the best innovative talents.
1. Inviting internationally famous professors for lectures

2. Attending international conferences
3. Long-term abroad visiting
