Three Bridges manager Paul Faili will stay on as boss after coming back to steer his club to safety.
A 2-0 win last week away to Whyteleafe got them over the line to stay in the Bostik League for another season.
This was followed on Saturday by another 2-1 win at home to Whitstable Town, despite being reduced to nine men.
The result means Bridges have finished 14th out of 20 teams and were a comfortable 14 points above the relegation zone.
It was a different situation in March with Bridges lying bottom of the form table and were third from bottom in the division with just one point out of a possible 27.
Previous manager Martin Dynan left the club and chairman Faili put himself back in charge of the team and in nine matches gained 14 points out of a possible 27.
