Group 1
I-70 forms a physical barrier that disconnects the local street network and neighborhood fabric, forcing local residents to use it as a local route, and causing an uneven pattern of growth in Denver.
Problem Statement
Establish a network that favors neighborhoods and enriches multi-modal mobility. Reconnect local streets to allow for improved movement within neighborhoods and the greater metropolitan region without reliance on the interstate. Amend zoning plans to create a more robust, and local, commercial environment. Enrich the street network to accomodate a dense and efficient pattern of growth.
Vision Statement
EST. COST
$
Re-appropriate federal funds from I-70 to improve local street network Prioritize I-70 as a through-traffic corridor and limit access on & off Enrich local connectivity to create a more robust local network Promote the efficient growth of Denver evenly through its fabric Strengthen and expand existing commercial corridors Emphasize Fastracks/TOD as growth epicenters, expanding tax base

Partial Cover Lowered/Tramo a Desnivel Parcialmente Cubierto
Some of the input received from community stakeholders has been that the alternatives currently being analyzed do not satisfy the interests of the surrounding neighborhoods. Taking this into consideration, the project team developed a new alternative that includes partial cover over a section of lowered highway. This alternative lowers the highway below ground, allows for an area of green space, and provides north/south connections in selected locations.
Algunas de las aportaciones recibidas de los interesados de la comunidad expresan que las alternativas que se están analizando actualmente no satisfacen los intereses del vecindario circundante. Tomando esto en cuenta, el equipo de trabajo del proyecto desarrolló una nueva alternativa que incluye un tramo de la autopista parcialmente cubierto. Esta alternativa baja la autopista a desnivel, permite tener un área verde, y ofrece conexiones norte/sur en determinadas ubicaciones.
