The railing is actually being installed for a new spa treatment that is guaranteed to keep guests from turning into the Hulk during the hot summer months. Universal is offering a place for guests to sunbath in the shallow water where every few minutes they get a soothing massage as the Hulk roars overhead shaking the ground around them. Hulk hands with special lotions inside that will treat your trembling hands will be available as an up charge. Complimentary Green Tea will be served by mutants to help digest the rage. "The Hulks Lullaby" water treatment will be available from June 1st to September 1st.
But its probably just for the extended queue...
But in all seriousness please let them be temporary!
