HOUSTON – Preservationists are trying to save some of Houston's most historic streets.

The intersection of Wilson and Andrews, just west of downtown, is paved with bricks laid by free slaves around the time of the Civil War.

The city needs to replace the sewer lines underneath, and has promised to lay the bricks down just as they are. However, members of the Freedmen's Town preservation Coalition want crews to instead dig under the sidewalks, leaving the streets intact.

Coalition members met with Mayor Parker Tuesday night to discuss micro tunneling. They said the mayor expressed concern over the extra cost, but said she has not ruled out the option.
