Has anyone considered making ploppable crosswalks for roads/ OWR's and Avenues? Like the ones found at interesctions but with maybe a hanging stoplight that you could plop over a normal tile?
Do you mean as a puzzle piece, or as a transit-enabled Lot? If you are looking for a transit-enabled Lot, there are a few on the STEX. I haven't seen any on the LEX, unless it was cleverly hidden in a download. Be aware, that transit-enabled Lots block road access to 1-tile wide Lots if the transit-enabled Lot is placed in front of them. That is something that cannot be fixed, except by game's original programmers.
