As the I-25 South Gap project enters its fourth year of construction, more than 3,251 people have invested 1.3 million hours to construct safety and travel reliability improvements along Interstate 25 between Castle Rock and Monument. This Colorado Department of Transportation project – in partnership with Kraemer North America – remains on time and within budget as it enters the final year of construction.
The 18-mile I-25 South Gap project will deliver a new Express Lane in each direction, wider shoulders, five new bridges, four new wildlife crossings, 28 miles of deer fencing, a southbound I-25 truck climbing lane at Monument Hill, a southbound I-25 chain up station and improved technology. The entire project is expected to conclude in November 2022.
Motorists can expect to see paving operations and crews finishing bridge work (specifically in Larkspur and Monument), which may require I-25, ramp and bridge closures. In addition, motorists will see wider travel lanes as crews eliminate barrier through the I-25 South Gap work zone. Although travel lanes are becoming wider, it is still vital for motorists to heed the posted speed limits, keep a safe following distance and never drive distracted or impaired.
ADDITIONAL I-25 SOUTH GAP PROGRESS
| Project promise | Progress as of Sept.1, 2021 |
| Bridges: Five bridges will be reconstructed as part of the I-25 South Gap project. | From north to south:
|
| Paving: All lanes will get new pavement. The project includes 822,000 tons of permanent asphalt. | To date, 620,000 tons of asphalt placed; 75% of paving complete. |
| Advanced technology: Crews are working to modernize communications and power along the corridor to enable future advanced technology. Part of this advanced technology comes in the form of new fiber-optic cable. | Crews have relocated nearly 90,000 linear feet of existing fiber-optic line that was beneath I-25. |
|
Wildlife safety: Four new wildlife underpasses are being built with the expectation of delivering a 90% decline in animal/vehicle collisions along the I-25 South Gap corridor. These full-span bridges were designed in partnership with the Colorado Division of Wildlife specifically to accommodate animal crossing. Also includes 28 miles of deer fencing. |
23.5 miles of 28 miles total of deer fencing installed; four wildlife crossings complete. |
| Workforce: Investing in infrastructure also means investing in small businesses and people. |
