通れるの？

運河にかかる橋の上から、ふと見ると....

When I saw something on the bridge of a canal....

あっ、船だてか、通れるのかな

I found out this boat coming here...

But I thought it was difficult to come through under this bridge and the narrow canal!

えっ、本当に通れるの

Can you really come through????

通れるというか、通したね

It didn't "come through" but "make oneself  come."
