Lane passed over promenades (10)
I believe the answer is:
esplanades
'promenades' is the definition.
(esplanade is a kind of promenade)
'lane passed over' is the wordplay.
'over' indicates anagramming the letters.
'lane'+'passed'='lanepassed'
'lanepassed' with letters rearranged gives 'ESPLANADES'.
(Other definitions for esplanades that I've seen before include "go to seaside resorts for such" , "Places to stroll" , "seaside walks" , "Seafront walks" .)
