Introduction

CSX has reopened the Howard Street Tunnel in Baltimore after completing a $450 million expansion project.

Main Content

Project Overview

The project aimed to modernize freight-rail transportation along the East Coast. The Howard Street Tunnel was originally built from 1890-95.

Project Details

The expansion project was completed ahead of schedule. With the tunnel project completed, and once additional clearance projects are complete in early 2026, a key Interstate-95 corridor bottleneck will be cleared.

Economic Impact

The project is intended to boost Maryland’s economy and the nation’s supply chain.

Operational Improvements

Double-stacked intermodal trains will move through Baltimore. Double-stacking is a more cost-effective way to transport freight by rail compared to trucks.
