In new street additions, Meili built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Govardhan built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and La Ceiba built increasingly disconnected streets over time. For the full network, Meili grew more disconnected from 1975 through 1991-2005, then improved, while Govardhan became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and La Ceiba became progressively more disconnected. Notably, Meili had a more sprawly network than La Ceiba in 1975 but the two have since reversed their relative ranking.
