I believe each bridge has a maximum value for fully repaired. Lowest I have seen is 50. Also I have found that only one regiment can be flagged to repair the bridge in a stack. I can't remember if there is a similar limitation on attacking the bridge.

Here is the official rules governing repair:

By default, a bridge must have a nonzero strength before it can be crossed by units and any bridge that has been damaged cannot be repaired. When the optional Bridge Limit and Repair rule is in effect, there are two changes that occur.

The first change is that there are minimum strength values that the bridge must have to support movement depending on the type of unit. These values are based on the Maximum Bridge strength value determined by Parameter data.
• A bridge must have a strength of at least 1/4 the maximum to carry infantry units.
• A bridge must have a strength of at least 1/2 the maximum to carry cavalry units or leaders.
• A bridge must have a strength of at least 3/4 the maximum to carry artillery or supply wagons.
For example, if the maximum bridge strength is 200, then a bridge must have a strength value of 50 to carry infantry, 100 to carry cavalry or leaders, and 150 to carry artillery or supply wagons.

The second change is that it is possible to repair bridges using infantry or cavalry. You use the Repair Bridge option of the Command Menu in the main program to toggle the state of units that you want to repair a bridge. There are several requirements for this:
• The unit doing the repair must be in column and must be facing the bridge.
• The unit cannot be Disrupted or Routed.
• The unit cannot have moved, fired, or meleed in that turn.
At the beginning of each subsequent turn, a calculation is performed to determine how much repair is achieved. For each 100 men repairing, the Repair bridge parameter value is used to determine the gain in strength of the bridge. Once the bridge reaches the maximum strength, it cannot be repaired any further.

I found out the hard way the repair level restrictions work.[:)]
