Back alley shortcut (裏路地抜け道) is the small corridor between the buildings of Ennerdale Street that is featured in Resident Evil 3.
The alleyway consists of a narrow dimly lit path.
A Zombie can be seen in the window of the building, but it can never attack the player or be killed (This zombie disappears after the Zombie horde breaches the Sales Office, suggesting that it was among them). The player must proceed down this alleyway to reach the entrance to the sales office.
There's nothing to examine.
