I-15 Reopens to Full Capacity in Las Vegas

News Summary

Interstate 15 has reopened to full capacity, enhancing traffic flow for summer travel. The renovation project, known as ‘Dropicana,’ was recently completed, allowing five lanes in each direction. This upgrade coincides with significant events in Las Vegas, improving access for attendees. While the main work is done, further enhancements are planned, ensuring continued improvements in the area.

Las Vegas

Interstate 15 has returned to full capacity as of Friday morning, marking a significant milestone in the ongoing renovation of the interchange with Tropicana Avenue. As a result of the major “Dropicana” project, drivers can now utilize five lanes in each direction, improving traffic flow just in time for the bustling summer season.

The Nevada Department of Transportation (NDOT) recently completed overnight closures of I-15 to finalize essential work on the freeway. This included the installation of vehicle detection loops on key ramps and the necessary striping for the newly created lanes. Following these enhancements, the interstate, which had been limited to four lanes in each direction since 2023, is once again fully operational.

The “Dropicana” project, which commenced in 2022, involved extensive construction efforts that included the demolition of the Tropicana overpass. Over the past three years, crews have been working diligently to widen the interstate, resulting in additional capacity and the construction of new ramps for better accessibility.

Project Details and Impact

The estimated cost for the entire project is approximately $382 million. A critical part of the renovation involved demolishing and reconstructing the Tropicana bridge to render it wider and taller. The project also featured the addition of a Harmon high occupancy vehicle (HOV) half-interchange, allowing for improved traffic management.

As of now, the northbound I-15 off-ramp to Tropicana has been widened, and a new on-ramp from Tropicana to southbound I-15 has been built. The reconfiguration of Dean Martin Drive, including the addition of Joey Bishop Drive beneath Tropicana, also plays a pivotal role in improving the overall traffic flow around this busy intersection.

Significance of the Reopening

The reopening of I-15 to full capacity comes at a strategic moment, coinciding with the start of the Electric Daisy Carnival (EDC), which is expected to attract around 175,000 attendees over the weekend. NDOT has indicated that the restoration of all lanes will offer relief for drivers as they navigate through the busy summer travel season, particularly during the Memorial Day weekend and the festivities surrounding EDC.

Future Work and Considerations

Despite the positive news about the reopening, NDOT has indicated that further work is still ongoing. This includes widening projects on Tropicana west of I-15 and additional improvements on Dean Martin and Harmon near the freeway. Paving closures on I-15 are expected to occur later this summer as these enhancements continue.

It is important for drivers to note that some features, including turn lanes from Tropicana, will remain limited to one lane due to ongoing median work. Additionally, the on-ramp to northbound I-15 is still operating at a reduced capacity as construction continues in that area. NDOT has assured the public that the total reconstruction of the I-15-Tropicana interchange is on track for completion later this year.

In summary, the completion of the Dropicana project marks a significant improvement in local infrastructure, enhancing the capacity and functionality of a vital transportation route in Las Vegas as the city gears up for a busy summer season.
