Alleyscape and Breezeway Project Update

Thank you for supporting 
Downtown businesses 
during this construction time! 

Phase 2 of Alleyscape and Breezeway Project is Substantially Complete!

Thank you to DeFalco for substantially completing all three blocks in one year and for being there to support business and property owners through out the project! 

It is an exciting time for the Alleyscape and Breezeway Project as it finishes on the west side in 2017. The City of Longmont, in coordination with the Longmont Downtown Development Authority, contracted with DeFalco Construction Company to complete Phase 2 of this improvement project. The Alleyscape construction was completed in 2013 on the east side of Main St. on the 300, 400, and 500 blocks and Phase 2 work was targeted for the 300, 400, and 500 west side of Main St. blocks in 2016. The construction focused on the alleys, breezeways and parking lots to further support the growth and development of downtown Longmont. Infrastructure goals included:

  • Addressing drainage problems
  • Burying overhead utility lines
  • Opening up breezeways
  • Creating a pedestrian/shopper friendly environment
  • Enhancing alley function, character, and level of finish

The LDDA, City of Longmont, and DeFalco Construction are committed to keeping you informed of construction schedules, parking restrictions, street closures and any other impacts the project will have on visitors, businesses, residents, and employees downtown.
