Line Editing

I'm working on developing a more complete road network. For this I'm using the distance tools from spatial analyst. After this is done, I convert my raster file to vector and here is where my problem appears. There are gaps in between what should be junctions and I thinks this is explained by the distance between the centroids of the pixels.

I'm using the exted tool to complete these missing gaps, but it doesn't work for all the gaps. Is there another tool, or script that can be used to get this done properly?

Thanks

How big is your raster grid data?
You can reset your raster cell size less than your line feature class tolerance, then convert that raster to line feature class and it won't have gaps, but the progessing time should be long. So you can just select lines with gap, then go back to select the related raster pixes by using the line ID - only reset those cells to small value, then convert them to lines.

Have you tried a topology? Those are good for finding & fixing errors.
