Passage:

River Market Renovation
The council newsletter describes a renovation of the river market. The first change was practical: stall owners were asked to move their tables two metres back from the canal edge so emergency vehicles could pass. Next, the council replaced the old metal awnings with lighter fabric canopies because the metal trapped heat. After that, new signboards were installed above each aisle so visitors could find fish, fruit, cloth, and spices without asking for directions. In the final week, a short loading lane was painted near the back gate so delivery vans could unload before 10:00 a.m.

According to the passage, which change happened immediately after stall owners moved their tables back from the canal edge?
