This paper describes tunnel cross-section measurement system using a Mobile Mapping System. The topography of Japan is mountainous, so there are many tunnels in Japan and total length of Japanese tunnel on road is over 3000 km, and 80 km tunnel are built every year. As far as some old tunnels are concerned, collision accidents sometimes happens because of old tunnel's diameter shortage. Thus, tunnel cross-section measurement method without highway traffic regulation is demanded nowadays. The proposed Mobile Mapping System (MMS), featuring the carrier phase D-GPS/DR (Dead Reckoning) combined navigation system and the GPS-Gyro/IMU(Inertial Measurement Unit), performs highly accurate positioning performance in centimeters and posture estimation at 0.073[deg](1σ) for heading, 0.064[deg](1σ) for pitch and 0.116[deg](1σ) for roll. The proposed Mobile Mapping System that can measure 3D shape of the tunnel at 40 km/h cruising speed without traffic restriction is proved to be valid and effective for tunnel cross-section maintenance through field experiments
