Looks a lot like Golden Gate in San Francisco. I personally like Golden Gate a lot so it was very fun for me to see 25 de Abril. It's moderately long and it stand pretty high. If you're staying in Lisbon I'd recommend you to go see it and maybe take a ride over it. The bad thing i s that pedestrians cannot cross it. It would be very nice to go for a walk over it, like you can do on Golden Gate.
