Power was restored to several properties in Woodbridge Road, Ipswich, in the early hours of Monday following an electrical fault underground overnight.
The road is still partially closed, however, between Argyle Street and Warwick Road while work takes place at the scene, with temporary traffic lights in place.
These are expected to be in operation during rush hour, which is expected to cause some heavier traffic than usual.
The incident was reported at 10.30pm yesterday and was caused by a fault on an underground electrical junction box. It is also thought to have caused some damage to the pavement.
A total of 23 properties lost power initially as a result of the explosion, but power was restored to all homes in stages between 3.30am and 4.30am today.
Speaking last night, a spokesman for UK Power Networks added: “Our engineers were swiftly at the scene to assist the emergency services in making the area safe.”
