Dunkirk Scenario 3 Bridges?

[Blackcloud6]

Am I correct that "the bridge" that the scenario calls out in "other" of the scenario description is the one hex 0509 of Board 125?

Am I also correct that the small brown bridges in hexes 0701, 0502 and 0513 are footbridges?  That the lines leading to these footbridges are trails?  

Thanks in advance.
