US 50 & CO 115 Roundabout in Penrose

Weekly Traffic Impacts - April 7 to April 13

Ongoing Traffic Impacts

• Lane closures in both directions of CO 115, traffic shifts and changing conditions will exist Monday to Wednesday
• Starting on Wednesday evening (April 10), the southbound lane of CO 115 will be closed 24/7 within the project limits and alternating directions of traffic will be routed into the open northbound lane
• The closure will be managed by temporary signals at each end of the proposed roundabout area
• Motorists can expect short delays during these alternating traffic holds
• Working hours are 7 a.m. to 5 p.m. Monday to Friday
• The project limits on CO 115 extend from MP 12.76 to MP 14.01
• Lanes are narrowed and caution is advised
• Construction devices and barrier are in place to maintain safety
• Flaggers, signs, and message boards exist to alert the public to closures and restrictions within the work zone
• Construction schedules are weather dependent and subject to change

• Starting the evening of Wednesday, April 10, eastbound US 50 off-ramp traffic to CO 115 will be routed onto onsite detour pavement
• The new off ramp detour configuration will be in place 24/7 during construction of the roundabout
• Caution is advised as the new off-ramp will be shorter and require a sharp 90 degree turn
• No lane closures are expected on mainline eastbound US 50
• Working hours are 7 a.m. to 5 p.m. Monday to Friday
• The project limits on US 50 extend from Mile Point 289.50 to MP 289.84
• Traffic shifts, narrowed lanes and reduced speeds may exist later in the project
• Flaggers, signs and construction devices are present to alert the public to the work zone, closures and restrictions
• Please exercise caution as motorists famiiarize themselves with the new off ramp configuration 
• Construction schedules are weather dependent and subject to change

General Impacts, Schedule & Scope of Work

• The project began on March 4 and has an anticipated completion date of late October
• Starting on April 10, CO 115 will be in a single lane configuration within the work zone, with alternating directions of traffic managed by temporary traffic signals
• The single lane configuration consists of a 24/7 closure of the southbound lane with alternating directions of traffic routed into the open northbound lane
• Motorists can expect short delays during alternating traffic holds
• The temporary signals will be installed on each end of the roundabout area to manage alternating directions of traffic into the open lane
• No immediate lane closures are expected on eastbound US 50
• Starting on April 10, the eastbound US 50 off ramp to CO 115 will be in a 24/7 temporary configuration onto detour pavement
• The new off ramp detour configuration will be in place 24/7 during construction of the roundabout
• The project limits on US 50 extend from MP 289.50 to MP 289.84
• The project limits on CO 115 extend from MP 12.76 to MP 14.01
• Working hours are 7 a.m. to 5 p.m. Monday to Friday
• Working hours will be extended during the summer months
• This state funded project is designed to improve safety and traffic flow by adding a roundabout
• The roundabout will be on the south side of CO 115 and intersect with the on and off ramps of eastbound US 50
• No changes will be made to the westbound US 50 on and off ramps
• Other work includes adding a concrete island and truck apron, and installing curb and gutter, lighting, and traffic signs
• Roundabouts are proven to be a safer and more efficient method of traffic operations at certain intersections
• Construction schedules are weather dependent and subject to change
