Stop boards and a temporary dam are in place on the Grand Western Canal and holding back water after yesterday's catastrophic breach, engineers have said.
Devon County Council opened the road which runs between Halberton and Sampford Peverell this evening, around 24 hour after it was shut because of fears another leak might flood houses in the village.
Yesterday a large section of the embankment on the north side of the canal came away, draining a two-mile stretch of the waterway into fields.
Workers were seen using a crane to lower several tonnes of earth into the canal earlier today to create a dam.
The council said this evening that stop boards at Manley Bridge and the additional damming on the other side of the breach are now
secure and not leaking - isolating the breached section.
The water level in the lagoon to the Tiverton side of the remaining embankment is dropping slowly.
Access to the breach in the embankment along the towpath has been sealed off, as this area is still unstable.
It is thought that hundreds of fish and other marine life has been affected by the incident. There are also fears that the lagoon will have to be drained before repairs can be carried out.
Engineers are due to reassess the situation in the morning.
