The corridor's telemetry settled the first argument — Marine Drive to Versova in 19 minutes against 53 on day one. Four arguments remain open.

Induced demand vs pricing. Earlier phases hit design capacity in eleven months against a seven-year projection; the electronic tolling makes congestion pricing technically trivial the day it becomes politically possible. The commissioned study is deferral with a bibliography.

The bus lane's defence. 34,000 passengers on day one, schedules held through the peak — the transit concession works. Every future proposal to "temporarily" open the lane to cars is where the corridor's soul gets decided.

The koliwada ledger. Navigation channels, harbour upgrades and market redevelopments reach delivery deadlines this year; the fishing federations have said they will count stalls, not press releases.

The green line's maintenance. Seventy hectares of reclaimed public space — the largest addition since the mill lands — survives only as long as its budget lines do.

Cities are arguments that build themselves into geography. The sea, as ever, holds the review rights. Continuing coverage on our cities desk.
