CDOT representatives say the Berthoud Hill Climbing lane construction (southbound) was scheduled to begin on May 16. The work will happen at night and will involve the closing of one lane. The project will be significantly complete by December 2016. CDOT also announced we should hear if I-25 will be the recipient of two federal grants for the Phase I additional lane project (SH 14 to SH 402) by late August or early September.
