The Blue Line Bus Rapid Transit (BRT) Project in Indianapolis is a major transit initiative designed to provide faster, more reliable east–west service across Marion County. The corridor runs roughly 24 miles, linking the Indianapolis International Airport in the west to the Town of Cumberland in the east, passing through downtown Indianapolis. The line is planned to include approximately 30 station platforms, spaced roughly every half to one mile, along with upgrades to sidewalks, crosswalks, traffic signals, and stormwater infrastructure.
Project Cost and Funding
The estimated total cost for the Blue Line BRT Project is around $387 million. Funding combines federal, state, and local sources, including a $150 million Federal Transit Administration (FTA) Small Starts grant, local contributions from the City of Indianapolis and utility partners, and additional regional transportation funds.
Construction Approach
Construction began in early 2025 and is being executed in multiple segments to minimize disruption and manage the workload. The project includes roadway improvements, utility relocations, station construction, and installation of bus-only lanes in key segments. Construction activity has required lane closures along portions of Washington Street, with detours and temporary traffic adjustments to accommodate infrastructure work.
Timeline and Operations
Final design work has been completed, and construction is ongoing. The Blue Line is expected to begin revenue service around 2028, depending on the progress of construction and final approvals. Once operational, the line is expected to improve transit speed, increase ridership, and enhance pedestrian safety along the corridor.
Broader Context
The Blue Line BRT Project is part of a growing trend of Bus Rapid Transit projects in U.S. cities, providing high-capacity transit along major urban corridors. Projects like Indianapolis’ Blue Line and Denver’s Federal Boulevard BRT aim to reduce congestion, improve service reliability, and support sustainable urban transportation planning.
The Blue Line Bus Rapid Transit (BRT) Project in Indianapolis is managed by Stantec Inc., a global professional services and design consulting firm, which oversees construction management for the corridor. The project represents the city’s third BRT route, connecting to the Indianapolis International Airport, the existing Red Line, the planned Purple Line, and other bus routes.
The 24-mile, all-electric bus system follows the existing Route 8 corridor and is designed to provide more reliable transit service to neighborhoods with high concentrations of zero-car households. The Blue Line is expected to improve transit efficiency, accessibility, and connectivity across the Indianapolis metro area.
Project Scope and Partnerships
Stantec provides construction management for the roadway, stations, and utilities, coordinating overall integration alongside contractors Shiel Sexton and Shrewsberry. The project includes a 25% participation goal for disadvantaged business enterprises (DBEs) to promote diversity in the construction supply chain.
Key components of the Blue Line include:
Implementation of dedicated BRT lanes in strategic sections of the corridor.
Construction of station platforms, shelters, and associated amenities.
Upgrades to utilities, sidewalks, and traffic signals to support the new system.
System integration for communications, signals, and transit operations prior to service launch.
Construction Considerations
Building the BRT corridor involves navigating challenges such as avoiding utility conflicts, maintaining local access during construction, and ensuring functional integration of traffic and communications systems. The project is structured to allow phased construction to minimize disruption while maintaining progress along the 24-mile route.
The Federal Boulevard BRT Project in Denver follows a similar approach to other major U.S. transit investments, such as Indianapolis’ Blue Line BRT. Both projects focus on upgrading existing bus corridors with dedicated lanes, modern stations, and electric buses to improve reliability and service frequency. While the Blue Line has begun construction with an anticipated opening around 2028, the Federal Boulevard corridor is advancing through design and preconstruction planning. These parallel efforts highlight how cities are using BRT to modernize urban transit, optimize travel along key routes, and provide more efficient connections for daily commuters.
