El Paso County likely will contribute $15 million to the widening of Interstate 25 from Monument to Castle Rock, fulfilling the project’s $35 million local fundraising goal. The 2018 county budget, which commissioners approved unanimously on Tuesday, includes $7.5 million for the widening. The county also resolved to provide another $7.5 million for the project in the future. Overall funding for the widening of the “I-25 Gap” isn’t set in stone, but state and local officials now have identified the sources and amounts needed for the $350 million price tag.
