US 34 Timber Bridge Replacement East of Laird

About the Project

A planned winter shutdown is now in effect for the US 34 timber bridge replacement and roadway improvements east of Laird, which began in April. This shutdown is essential to ensure the safety of both the traveling public and construction crews during winter weather conditions. During this period, a reduced speed limit of 50 MPH will be in effect.

Work is set to resume in late April of 2025. Crews will conduct paving and striping operations, as well as install new guardrails at both bridges.

During the 2024 construction season, construction crews removed the two aging existing timber bridges to construct two new concrete bridges in their place. Crews created an off-site detour that was used to divert traffic during bridge construction to minimize disruptions to traffic flow.

Project Benefits

• Concrete is known for its high compressive strength, making it capable of supporting heavy loads. It also has excellent durability, resisting deterioration from weather, chemicals, and abrasion over time. This longevity reduces the need for frequent maintenance and repairs compared to other materials.
• New pavement markings and delineators will provide visual guidance to motorists. The installation of guardrails will increase motorist safety. In addition, erosion control measures will prevent eroded soil from entering the waterway under the bridge.

Work Schedule

• Monday through Friday, 5 a.m. to 7:30 p.m.

Traffic Impacts Next Season

Motorists can expect the following impacts during the period of construction:

• A speed reduction of 35 mph will be in place through the construction zone
• A 12 feet width restriction and a 100 feet length restriction in place through the project area
• Traffic will be guided by flaggers through alternating lane closures
• Trucks entering and exiting construction zone
• Refer to COtrip.org for real-time travel conditions and road closures
