A multiyear field project focused on long-distance causeways between Uci and Cansahcab in Yucatan, Mexico, supports their use for processions and pilgrimages, their role in the creation of multisite polities, and their involvement in the constitution of local authority. Yet details of the causeways’ construction suggest that people contested this authority. Work was central to these dynamics and comes in the form of labor as practice, investments in the maintenance of relations with other-than-human beings, and the ways that causeways produced embodied experiences that were ideal for their use in pilgrimages.
