Each of the corridor-wide improvement strategies considered during the First Tier Study of I-70 had some benefit. However, the widening and reconstruction strategy presents the best balance for achieving future goals. This strategy will:

Meet the long-term travel and safety needs for the corridor
Respond to public concerns
(widening favored over other options by two-to-one)
Preserve the system by replacing existing I-70 pavement
Lower annual operations and maintenance costs
Reinvest in the existing system
Be built in usable increments, yielding earlier benefits
Incorporate high-tech improvements
(weigh-in-motion for freight carriers, highway advisory radio, remote weather sensors, variable message signs)
Improve incident management

Additionally, this strategy will allow MoDOT to construct improvements while maintaining four lanes of traffic at all times. This alone is a tremendous benefit to the traveling public, considering the many years it will take to complete I-70 improvements. The widening and reconstruction strategy will safely accommodate cars and trucks, allow for future options in the median and provide superior management of traffic during accidents.
