Rockies fans headed to games this season will get to see the transformation of the old West Lot, where work has been underway since the team last played to transform the space into a three-building project set to open in 2021. When finished, the old lot at the southwest corner of 20th and Wazee streets will be a mixed-use project that will house the team’s hall of fame. Denizens of the ballpark neighborhood may be aware of all the work that has happened since crews fenced it off last September in advance of its transformation, but for fans that haven’t been to LoDo since the end of the 2018 season, here is the latest: Excavation work is still underway, but support pillars are rising as concrete is poured for the two floors of underground parking that will eventually host 420 spots. Three tower cranes have been erected around the site.
