This [1] is a good overview of the general costs and trade-offs of various kinds of bike lanes in the US. Some benchmarks to get a feel for ballpark numbers [2] for US cities to start an analysis in your area. Basically in built-up areas in the US, options are pretty limited without overwhelming public demand for ejecting car drivers from an area in favor of pedestrian and cycling traffic. I'm still looking for what it looks like when a city design favors pedestrian, cycling, e-assisted human-powered/assisted mechanisms (e-bikes, scooters, Segways, skateboards, skates, etc.) traffic, then on-call PRT-to-GRT-scale people/cargo/freight movers within neighborhood-scale distances in dense (40-50,000 people per sq km) developments, subways for inter-neighborhood connections, and vehicles are restricted to the city borders (kind of like restricting specific traffic at the network border) for large-scale commercial cargo and passenger transport. I'd like to see a breakdown of where the capex and opex expenses come from for elevated and subterranean bike lanes. Building up and down seems currently a significant cost barrier.
