The shelter on Marine Parade was reopened last week just days after a second shelter, on Leigh's Cinder Path, was reopened after a five-year closure.
Closed after damage caused by vandals earlier in the year, the Marine Parade structure offers a sheltered spot for walkers to enjoy estuary views.

Southend Green Party campaigner Simon Gittus was one of those who pushed for the repairs to be completed and thanked residents for their support on the issue.
He said: "It looks fantastic, and the team have done a brilliant job restoring it.
"Thank you to residents for flagging the issue with me.
"I'm glad it's back open for everyone to enjoy, and we'll keep working to make Leigh even better."
The shelter, which is more than 100 years old, was targeted by vandals earlier in the year and has been closed for repair works ever since.

Following the most recent attack, Southend Council organised the repairs needed for it to be returned to public use.
Stuart Allen, Green Party councillor for Leigh, said: "We've worked hard to get the shelter fixed and it looks great again.
"Thank you to all the council staff and joiners who brought it back to its former glory."
The Green Party in Southend has long pushed for more to be done to protect the historic shelters, which are dotted along the seafront.

The Cinder Path Shelter, which was reopened earlier this month following its five-year closure, is a particular focus of calls for protection, with campaigns stretching back to 2007.
Daniel Cowan, Labour leader of the council, said: "As part of our ongoing and planned three-year programme to revitalise our Victorian shelters across the city, we are pleased to confirm that the work at the Marine Parade shelter has now been completed.
"These shelters are a big part of our city's history, and regular upkeep ensures they remain safe and usable for everyone. It's important that we continue taking care of these structures so they can be enjoyed by future generations."
