The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Port Houston's project page describes "expediting the process to complete the work in 2029", a year rather than a day, so it sits at the end of that year.
Port Houston’s own release dating the halfway mark this pin’s description rests on: "Port Houston-led project dredging of the Houston Ship Channel is complete", with the Galveston Bay reach widened from 530 to 700 feet, while "some beneficial use aspects of the project remain under construction". The 2029 date is for the whole of Project 11, not this portion.[1]
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
