Contact
Correspondence about the site's contents reaches one address.
contact@sustainablehighways.org
The mail that improves the site names something specific. A correction works best when it quotes the sentence and points at the document showing the error. A sourcing problem is worth reporting when a citation has moved, been withdrawn, or does not support the claim resting on it. A coverage suggestion is worth sending when a study, dataset or agency report should have been read for an article and was not.
Everything sent to the address is read, though a reply is not promised, and a correction may land in the copy before an answer lands in an inbox. Requests to insert links, to place paid material, or to have a product or firm covered promotionally receive no response. How correspondence about an error is handled is set out in the editorial standards, and what the site is for is in the about page.
