This is a very long piece of text where the term "fast-track" is used in various combinations (as a verb, as a qualifier). I am looking for a Spanish equivalent other than (as a qualifier) "rápido/veloz". In the case of "fast-track goals" I am prone to "metas presurosas", but I would appreciate your suggestions to improve the register as much as possible. Take into account that, as a verb, I have been alternating "apresurar, agilizar, urgir, among others). I know that "vía rápida" is often used, though it does not sound convincing (IHMO) for this text, unless combinated with "investment" (see below). Thank you all in advance! Here are some sentences:

Reaching the fast-track targets will effectively end the epidemic.
The economic return on fast-tracked investment is expected to be 15 times
