In Brief

From Virginia to Texas, States across the country are building durable,cost-effective bridges using high-performance concrete (HPC). To find out details about HPC bridge projects, learn the answers to frequently asked questions about the technology, or find a list of useful publications on the subject, consult HPC Bridge Views. The bimonthly newsletter is published by the Federal Highway Administration (FHWA) and National Concrete Bridge Council (NCBC). For a free subscription, contact Shri Bhide at NCBC, 847-966-6200, ext. 385 (fax: 847-966-9781; email: ncbc@portcement.org). Previous issues of the newsletter can be found on the Web at www.portcement.org/br/newsletters.asp.

A prototype version of QuickZone, a new work zone delay estimation software developed by FHWA in cooperation with Mitretek Systems, is now available on the Web for use and assessment. The software can be downloaded at www.tfhrc.gov/its/quickzon.htm. A user need only have Microsoft Excel 97 or higher running on a Windows-based PC to use the QuickZone application. The software allows the user to compare the traffic impacts for work zone mitigation strategies and estimate the costs associated with these impacts. The costs can be estimated for both an average day of work and for the whole life cycle of construction. Version 0.99 of QuickZone is scheduled to be released in April 2001. For more information, contact Deborah Curtis at FHWA, 202-493-3267 (fax: 202-493-3419; email: deborah.curtis@fhwa.dot.gov).
