I got deep in the replies on Twitter arguing about the community path. As you said, their arguments against it were all over the place (“just transfer from the bike to the train, bike routes should always be on roads, the community path is unsafe at night” ?!?!). Seems so myopic to blame the path, which was like 2% of the project cost, for the cost overruns. Transit advocates and bike/pedestrian advocates should be allies when it comes to getting people out of cars and increasing mobility. But even setting that aside, if you think of the GLX as a multimodal project that involves two separate train and bike components, you quickly see the cost of the path is neither here nor there for rail cost inflation. If you want the next light rail project to learn lessons from this one, the relevant comparison is the 98% of the money that went to the trains.
