Building Seattle's State Route 99 Supertunnel: Journey from light to light is a photojournalistic book documenting the building of the State Route 99 deep-bore tunnel in Seattle, Washington-a historical transportation megaproject. 'Bertha' was the largest-diameter Earth Pressure Balance Tunnel Boring Machine (EPB TBM) at the time of delivery, and this project is the largest-diameter completed tunnel to-date. The underground drive ran beneath the downtown of Seattle for approximately two miles. This project provided the city with a new safe route, replacing the 65-year-old Alaskan Way Viaduct. The Viaduct was a major highway but was damaged during the 2001 Nisqually earthquake and deemed unsafe should future earthquakes occur. Though intended to be completed in two years, the endeavor was complicated as the TBM suddenly halted shortly after starting her journey, due to overheating and damage to the machine. The TBM was rescued from 120 feet below ground, via an Access Shaft. Once repaired, returned underground, and tested, it continued its route until reaching the final exit zone at the North Portal near the Seattle Center complex, on April 4, 2017. Governor Jay Inslee and other officials inaugurated the new SR 99 tunnel with a ribbon-cutting ceremony on February 2, 2019.The Alaskan Way Viaduct, a city fixture for 65 years, was demolished over the summer of 2019. Now the waterfront is unobstructed and plans for the renovation of the area commenced.Catherine Bassetti was the official on-site photographer for the project. This book covers all aspects of this Project from 2014-2019, including six work zones, all major events, and milestones. Also included are interviews with both key personnel and crew members of many trades. It includes narratives from the Labor Union workforce and statements by State officials and major firms responsible for key engineering aspects. This book includes unique photographic coverage following both the building of the high profile tunnel and the human stories of those who ultimately made it a success.

The classic work on the evaluation of city form. What does the city's form actually mean to the people who live there? What can the city planner do to make the city's image more vivid and memorable to the city dweller? To answer these questions, Mr. Lynch, supported by studies of Los Angeles, Boston, and Jersey City, formulates a new criterion—imageability—and shows its potential value as a guide for the building and rebuilding of cities. The wide scope of this study leads to an original and vital method for the evaluation of city form. The architect, the planner, and certainly the city dweller will all want to read this book.

For a century, the route of Highway 99 has been the main transportation corridor in western Washington. Forest and farm products, fish, and families have all been a part of the flow of business and recreational travel between the Canadian border at Blaine and the Columbia River at Vancouver. What is now Highway 99 originated as a loose network of muddy roads connecting early settlements. With the dawn of the automobile age and construction of good roads, travel for business and pleasure began to shift away from ships and railroads to trucks and family cars. Roadside services developed within and between towns to cater to the new type of travelers--as many as 1,300 "gas, food, and lodging" businesses lined Highway 99, ranging from primitive auto camps to luxury hotels and from simple burger stands to roadside eateries shaped like giant tepees and igloos.

TCRP report 155 provides guidelines and descriptions for the design of various common types of light rail transit (LRT) track. The track structure types include ballasted track, direct fixation ("ballastless") track, and embedded track. The report considers the characteristics and interfaces of vehicle wheels and rail, tracks and wheel gauges, rail sections, alignments, speeds, and track moduli. The report includes chapters on vehicles, alignment, track structures, track components, special track work, aerial structures/bridges, corrosion control, noise and vibration, signals, traction power, and the integration of LRT track into urban streets.
