An underground explosion at Dunfermline Bus Station was caused by a traffic maintenance system blowing up.
A series of loud bangs were heard on Queen Anne Street shortly after midday before a manhole cover flew through the air.
Eyewitnesses reported seeing smoke coming from the hole in the ground as police and fire crews raced to the scene.
Police threw up a large cordon around the area and blocked vehicles from heading towards the bus station on Carnegie Drive.
Heavy traffic quickly built up in the surrounding area with lengthy tailbacks on St Margaret’s Drive.
Buses were left unable to stop at the station and were temporarily diverted to St Leonard’s depot as James Street Bus Station was also closed for around an hour.
A spokesperson for Scottish Fire and Rescue said: “We were called at 12.14pm of a traffic maintenance system box exploding and of reports of smoke in the area of Queen Anne Street in Dunfermline.
“Two appliances have been dispatched to the scene. There are no reports of any injuries as a result of the fire.”
Police Scotland said road closures were put in place while work was carried out to ascertain the cause of the explosions “and ensure the safety of the public”.
*UPDATE* It has been established that the issue was electrical and utility staff remain at the scene. Roads have been reopened and normal service has resumed at the bus station. Thank you for your patience while emergency services attended.
