Sometimes I might want to display my Micropolis city as a very long thin shape, and in that case I might not have enough of the tramway modules I made previously to run the whole length. They require lots of 1×2 grille tiles and a few other bits to make, which are not cheap. But I have found lots of flowers in three colours, lime green studs and green 4×4 plates from pick a brick hauls, so I decided to make some Boulevard modules which can extend beyond the end of the tramway to fill the 4-stud wide gaps in the middle of the roads.
