Dear Dr. Gridlock:

What is the status of sound walls being erected along Route 29 in the Ellicott City area? After considerable activity, progress seems to have come to a standstill, and the project is only partially completed.

I suspect some sort of contract dispute or financial difficulties on the part of the contractor. There are at least two expensive cranes that have been idle for over two weeks.

No contract problems; construction has been slowed by the abnormally heavy October rains, according to the Maryland State Highway Administration.

There are two sound wall projects along Route 29 in the Ellicott City area:

* Along southbound Route 29, between Frederick Road and south of Route 103, the state is constructing sound barriers for about a mile and a half to help protect the High View and St. John's Manor subdivisions. That project should be completed by the end of the year, weather permitting, with final landscaping done next spring.

* Along northbound Route 29, between Route 175 and Diamondback Drive, the state is putting up sound walls on a smaller scale, for less than half a mile. That project should be done by the end of November, weather permitting.

The cost of the first project is $6.5 million, and the second is $1.4 million. The state pays for 80 percent of these noise projects, with Howard County contributing 20 percent.

Update on Arundel Projects

Here is an update on two of the largest state highway projects in Anne Arundel County:

(1) A new interchange at the junction of Routes 2 and 50 will provide easier access for vehicles traveling to and from the two roadways in the fast-growing Parole area.

The $13 million project also provides improved connections at the confluence of nearby Routes 2 and 450 and Jennifer Road.

Construction started in spring of 2003 and should be finished by the end of this year. The project is running a few months behind schedule because of inclement weather.

(2) New bridges on Rowe Boulevard over College Creek and Weems Creek, leading to the statehouse, are on schedule. This project involves the replacement of the College Creek Bridge and redecking of the Weems Creek Bridge. Both are about 50 years old.

The state has sought extensive community involvement and pursued an extraordinarily long (two years) design phase to be sure the bridges are aesthetically appropriate for the major entrance to the state capital. "The bridges will look fabulous," says Dave Buck, a spokesman for the Maryland State Highway Administration.

The new bridge work will include bike lanes in both directions, connecting to existing bike paths. It is good to see consideration of bike lanes in road projects. With rising gasoline prices, more and more motorists are looking for alternative transportation modes.

This $30 million project began in April of 2004 and should be completed by the end of next summer.

Parents Can Teach, Too

Dear Dr. Gridlock:

The letter regarding 15 screaming middle schoolers causing problems on the Metro was sad in its conclusion [Dr. Gridlock, Oct. 16]. The writer thought that the "school staff should teach children how to behave on public transportation."

That incident occurred during rush hour, which leads me to think that it was not connected with a school-sponsored event.

Why is this something the school staff should teach? Doesn't anyone remember what parents are supposed to be for anymore?

Teaching manners, including behavior, starts at home. Parents, instead of taking responsibility for their children, are stepping back and letting the schools, states, churches and peers raise them.

Some parenting is woefully inadequate. Seems to me teachers could take a moment to talk about how to behave on public transportation.
