The intricate granite stone sidewalks and streets were designed by architect I.M Pei to resemble the scale pattern of the western diamondback rattlesnake.
Light rail service was added at 16th & California and 16th & Stout stations in 1994, creating a third transit hub along the mall.
RTD estimates the MallRide shuttle removes nearly a thousand daily bus trips from the streets of downtown Denver, reducing traffic congestion and improving air quality.
The second-generation "EcoMark" buses were introduced in 1999 and were series hybrids with batteries charged by a 70 hp (52 kW) 1.6-litre compressed natural gas Ford engine.
