Lee Carney struck his 52nd goal for Bridges in just under 200 games for the club which is a fantastic return for a midfielder.
But while his previous strikes have included some great goals, surely there have been none as sweet as this 78th minute volley as he ran to meet Allan Tait’s lay-back on the edge of the area.
But it all might have gone to waste as Hastings regained the lead and Bridges needed a second equaliser.
This time a less than spectacular scramble home by Sam MacVicar in the third of five additional minutes, the second successive match in which Bridges have snatched an injury-time equaliser.
A fairly scrappy first half saw United gave the better of the chances.
Sean Ray headed straight at Kieran Thorp from a corner by Sam Adams, who then saw a free-kick flick-off the top of the crossbar.
Taser Hassan was denied by the post and United’s best move of the half finished with Kyle Holden firing wide.
Tait fired just wide following a lovely ball from Williams Peauroux and Nathan Crabb had an angled drive tipped away.
Tony Garrod’s drive stung the hands of Hastings keeper Josh Pelling, while the half ended with MacVicar’s back header from Peauroux’s cross going just wide.
Bridges started the second half looking much better and Tait should have done better than hit the underside of the bar from Hakeem Adelakun’s superb cross.
Adelakun himself stabbed at another Peauroux cross and Garrod had a shot charged down, and then against the run of play, United took a 55th minute lead when Evan Archibald took advantage of a Callum Donaghey slip and passed inside to Adams, whose shot was brilliantly parried by Thorp only for Steve Brinkhurst to follow up and net.
There were chances at both ends as the game opened up and Matt Whitehead was proving dangerous on the left flank against his former side.
One of his crosses found MacVicar, but his header was comfortably handled by Pelling, while a good passing move ended with Carney firing just wide.
MacVicar had a free-kick blocked but then came Carney’s brilliant strike.
Both sides looked as though they might accept a 1-1 draw until slack defending ken to a simple goal for Hassan in the 84th minute.
But Bridges had been inspired by both Carney’s strike and the industry of substitute Ben Godfrey, and it was his determination test finally led to the ball running free for MacVicar to stab home from close range.
