For $10B we could build a new tunnel. Such a waste of money to funnel cars into the same bottleneck. Would make more sense to build a tunnel with an entrance by Liberty Science Center, built for large transport vehicles, then convert the Holland Tunnels into bidirectional pedestrian/bike/micro mobility tunnels. It would reduce maintenance costs associated with vehicles, such as road wear and emission ventilation. Can the Holland Tunnel take increased throughput of even heavier vehicles over the next 50 years?
